You are quite right, the corrugated area near the top of the mast is a weather shelter so that technicians working on the mast can shelter if bad weather comes in when they are up the mast. Also it allows staff to take a break out of the wind (which is vicious!) instead of going back to ground level. Incidentally, access up the mast is usually provided by a metal "basket" hauled up by a wire on a ground winch. Some unfortunate person has to climb up the ladder initially taking a rope to haul up the wire so the winch can be rigged up for use during the maintenance project. Climbing vertically takes good fitness! Ice is a big problem here. In the 1980s there was a severe icing episode (on the old mast which was later replaced). The ice was so thick that the guy wires could be clearly seen from down in Holmfirth. Unfortunately a sudden thaw in the weather caused tons of ice to slough off the guys which smashed into the building below. However, luckily it only damaged the standby generator plant and services kept going fed from the mains supply. Since then the building roof has been strengthened to give some protection from ice. You may notice some "knobbly" things on the guy wires. These are "helical strakes" made from plastic to stop an effect called vortex shedding which caused the guys to "gallop" or vibrate under certain steady wind conditions. It was quite frightening to see the guys whipping around and the associated movement of the mast under these conditions! Someone asked about "monitoring" - well at one time Holme Moss was a manned site that supervised the operation of all the BBC transmitters in Yorkshire, Derbyshire, Lincolnshire and part of Lancashire. Antennas were aimed at the various transmitters, which were unmanned, so that staff could listen to (or watch for TV) what was being broadcast. This supplemented the automatic monitoring equipment which reported faults, usually over telephone lines back to Holme Moss. Thanks for documenting your trip to HM - bought back happy memories from last century! Pretty much everything you talked about was accurate, by the way!
Peter, what an excellent and insightful response. Many thanks! Got me thinking about that corrugated breakout shelter up there though... Did you leave a little gas stove up there, or take a thermos? No technician should ever be without a brew (especially in poor weather). 😂 Thanks again, Mark.
@@m0wms I think probably a thermos and some sandwiches! I must admit I only ever took one trip up in "the cage" or basket on a relatively mild summer's day. But it scared me stiff so I just stayed in the cage admiring the fantastic view while the technicians/engineer jumped across the 2 foot gap to get onto the mast platform to do their work. The cage hung from a sloping wire on a pulley while it was pulled up by the winch wire which ran to just above the landing platform then down the middle of the mast to the winch on the ground. When you start off, the cage is perhaps 30m away from the mast and as you rise it gets closer to the mast, but never quite reaches it - hence the gap you have to swing across! One of the more demanding tasks is to apply grease to the stays or guy wires. The cage is rigged to run parallel to the guy and a rigger applies copious dollops of grease using his hands. The grease helps to reduce corrosion of the steel wires.

This reminds me of my time in Spain. I serviced some local radio stations who managed to get a rack space at a side where radio Nacional España had its transmitters. it was a site up a mountain top near Benidorm. You needed to remove any jewelry before entering the building. And the hairs on your arms went straight up when you did enter. One transmitter was 250kw I was told. It had several transmitters at that site. The tower was not that high, but it was packed with antennas in every direction. It also had its own generator as one transmitter was the emergency transmitter for Spain. The diesel fuel tank was made in a hole of the mountain and very large. Yes I do love this type of content. Keep this up. Great video.
A Navy Captain called my office one day and asked for any failed and weird antennas we had to install on his building. His idea was that the decoy antennas would keep the Soviets guessing at what all those antennas were about amongst the real ones.
I haven't seen your videos before, but as someone who works in the field of RF it's awesome to have videos like this to spread some light over things that aren't commonly understood in a way which is simple and makes sense. Thanks!
Indeed! I just found this video after another US engineer pointed to it from seeing a video where my Dad (current radio engineer) and I (total beginner at RF) toured the inside of a similar style tower site in the US.
Brilliant work Lewis. I was born in Lincoln and became very used to the Belmont site when travelling to the coast, strangely enough - I now live on the Norfolk Coast at Hunstanton and on a clear night I can see the lights of Belmont just across The Wash on the Lincolnshire Wolds and where I live, unless you use Sky - the Freeview signals come from Belmont. Interesting to see the Airwave stuff on the site. Back in the days when you could listen to the police signals on VHF and UHF (not that I did of course!) I tracked down most if not all of their repeater sites in Lincolnshire. Ahhh those days were fun.
Great video! Old antennas may simply be left on the tower because it's often too much effort and potentially cost to remove them, especially depending on where they are and whether any services have to be disrupted to get at them - e.g. you won't just turn off a major TV station so some riggers can climb past a DAB or digital TV antenna array to remove an antenna thats no longer being used (and this is more complicated now that antennas are transmitting multiplexes of multiple stations all at once...) Additionally, the company that once may have operated them may have gone bust, and the tower owner probably isn't going to make the effort/expense to remove the antennas either. That's all if it hasn't simply been forgotten about during upgrades, migrations, company mergers, etc.
I've worked in so many places (not broadcast) where stuff gets left behind like this, because ... what is it? What does it do? Who is responsible for it? Nobody knows. Lest it be important to somebody, though, don't touch it. The craziest example I've seen of this, though, was at a telco CO. There was a rack with a full rack-width hard drive ... ONE hard drive ... the width of a rack, and about 8U tall ... still powered on! That thing probably failed in the late 80s, but it's still there, because .. "Not my job" or "I don't wanna be the guy that broke something to do something that didn't need to be done."

Hi Lewis, I did something similar when I worked in a hi fi shop in Liverpool town centre called Hardman radio, not for tv but for broadcast VHF radio. I put a 4 element Yagi on the roof and a 3 element Yagi in the back of the shop with a wide band Labgear preamp in between the 2 antennas, this worked really well as the shop was about 60 foot long, so the FM reception was brilliant it also really helped to sell transistor radios as the customers where amazed just how good the cheap radios worked in the middle of the town centre. See you soon Dave. 😀
It is amazing how many different services are broadcast from a site. I have seen the antennas on the former World Trade Center in Manhattan, going to the observatory roof there before 9/11 in October 1981. Also been to the antenna site at West Peak near Meriden, Connecticut, for some of the FM Hartford CT area stations, at over 1000 feet above sea level, and finally the antenna site for Montreal Quebec, on Mont Royal site, above the city in 2008. Ray W2CH.
A friend (a former GPO/BT tech based at Telco Tower London) says that the Mini Tower at Heaton Park was part of the Backbone and Secondary for broadcast. Perhaps you might look into this. Great content, you can of course assume more content like this, would be most welcome.
This was an interesting video of this transmitter site. Brilliant work. I am an Armature Radio operator in the U. S. Always nice to see other transmitting equipment in different parts of the world.
Great episode! Yes, please more of this type of content! I’m in the U.S. , but I really enjoy your channel, and this episode is definitely one I found very interesting! Thanks for the great work you do and the extremely interesting content!!
Whomever it was that designed and constructed the anchoring did a damn fine job of it, and whomever performs the structural maintenance also "means business", as evidenced by the thoroughness of the application of the gunship grey paint, and the fact that absolutely no rust is visible, nor are any other signs of corrosion evident. At those heights/'altitudes', actually, one often sees streaks of rust, or other signs of corrosion, and that tower is pristine! Cheers!, and thanks for the upload!
Yes, when I worked there, the mast was painted I think about every 6 or 7 years. They used to use the same paint as on the Forth Rail Bridge, but these days it may be an epoxy based one. I remember at another site, we had 6 tons of paint delivered to put 3 coats on 4 tall towers. I was told that only about 1.5 tons would remain on the metalwork, the rest was solvent which would evaporate into the atmosphere! The paint is water-based these days so most of what evaporates is just H2O. When these masts are painted, the staff have to park their cars away from the building, otherwise they are likely to get spattered with paint that is impossible to remove without damaging the car's finish. (I know from experience!) The paint has a careful amount of thinner added to make it easier to apply, but not too much to cause the coat to be too thin. This is checked by microscope to make sure adequate thickness is applied. Painting is one of the more dangerous maintenance jobs because they have to get to all the nooks and crannies of the steelwork. This involves swinging down on bosun's chairs with a kettle of paint hanging from their belt and a long-handled brush in hand. Naturally, the adjacent antennas are powered down while they are working. I remember one painter asked if a large 1.5m diameter microwave dish was powered off for him to work in front of. He took some convincing that it was used for receive only and so the power was in the nanowatts or less! The guys or stay wires are regularly greased as well to prevent corrosion. Luckily, Holme Moss is well inland, probably 100 miles from the sea, so salt water corrosion is not a problem. Some transmittere sites near the coast are not that lucky.
To see Holme Moss defying the elements on a bleak day is a wonderful sight to behold. Loved this and your pirate radio videos. More please. I love broadcast related stuff like this. 😁
I have to agree, the fact that such a massive, and probably very heavy bit of kit can stand there and not blow over, makes it just as impressive as the aerials!
Fascinating - I work in telecoms so recognise some of the cellular and microwave links, I also had a stint doing student radio at uni so dabbled with a short range microwave link and the associated FM transmitter, but all of this gear is on another level - I'd hate to have to climb that mast though :D
I very much enjoyed this video. Please do more. I went to a local mast @ West Hoathley which carried all sorts of strange antennas including TETRA , took some pictures and the police were called! Have you ever tried explaining yourself to a brain dead non technical police woman who thinks Facebook has its own aerials? I have!
Awesome video Lewis! Definitely like to see more antenna arrays. Really enjoyed looking at this amazing structure. Interesting to see the damage inflicted by a wayward ice chunk on that microwave antenna.
Great Video Lewis. Thanks. I can confirm the necessity of the shelter having been stuck near the top of a tower crane during a sudden thunderstorm. Hanging on for dear life in freezing rain and high winds is not fun.
That's one very busy mast! So much good content in this video. I can't imagine how long it took to compile it. Well done, sir! Haskell - W5HLM New Braunfels, Texas
Great video Lewis! When you are in Holmfirth they say if you can’t see the mast then you know it’s raining. If you can see it you know it will start raining soon 😂
I have some photos you might like I took from one of the Arqiva auctions where I brought quite a few of the TXs recently used as part of the switch over project, and we had to remove them from the racks ourselves. So lots of RF kit. I now have a spare room full of TXs from Emley Moor and not exactly sure why I grabbed them but seemed too good an opportunity to let them pass 🤣.
Has been something I've seen as long as I can remember living in South Manchester Really interesting Lewis thanks for sharing and plese keep the intesting content coming 👍
Most of the info went over my head but I still found it really interesting, thanks Lewis! Hmm, the corrugated section, perhaps some secret military surveillance antennas? 😊
Excellent video Lewis 😀 . It reminds me of when I used watch BBC and IBA Engineering broadcasts to the trade in the 1980s when off school . Always fascinating stuff - thanks.
Remember them well. That monotone voice telling us that winter hill will be on low power this afternoon on all services while brierley hill will be qrp for fm services only. Lol.
I'd love to see a video on the RBS structure and maybe incorporate the RBS test! Love your work making broadcast technology accessible and understandable.
Videos like this are awesome, not long winded at all! For those of us not in the UK, maybe a video explaining how all the networks work together? You were using another name for a network I have no idea what it was, sounded like a company name. Does everywhere get BBC 1,2,3, etc but only Wales get the BBC Wales station? Those kinds of things.
Short version is that the entire UK gets the "national services", which consist of BBC R1, 2, 3 & 4 (on FM), plus 5 on MW and a few extras on DAB. These are transmitted from sites all over the UK, which are fed from London via a NICAM link. In addition, the UK is divided into "regions" with their own "local radio" station, BBC Essex, Southern Counties, or whatever. These are usually only transmitted from one or two sites to cover the smaller area.
Like others have said. Thank you for making these videos, I can now bore my passengers as I drive past these antennas. I would love to see whats inside the cabins around the base of these aerials, hopfully someone might be able to get you inside.
I really loved this video. I've often wondered how the TV broadcast and radio broadcast done in the UK. I use to live there at RAF Bentwaters in the early 1990's.
Brilliant video Lewis, very interesting and informative. I had the opportunity to go up the Mendip Mast (Pen Hill, Somerset) near me many years ago and was fascinated by all the equipment, would love to visit more of these installations.
Even though I’m “across the pond” in the USA, I’m very interested in any video you post. Doesn’t matter the subject. I especially like any commercial equipment along with Amateur Radio as I’m a ham too. (N6FRW). Thanks for all your videos.
The "Falling Ice" sign made me laugh. I visited NYC in 2016 and experienced 26" snowfall. A walk near any of the high rises bore risk and I saw 2 foot icicles crash to the pavement in front of me. Avoiding them became just another NYC skill.
Really nice video on what all these antennas do. Really, I thought it was like a two minute video when in fact it was 10 minutes, very informative very interesting thank you.
Really interesting video. Had no idea there were so many different services on one tower. Have you made any videos about how all of the services are managed at one site ? Or is that impossible due to security etc. ? Great episode 👍
if you ever wonder about how much EM can come off the primary transmission elements, I once saw a documentary where the crew was way up on top of Empire State in NYC right below its transmitter mast and you could see the wavering in the video from the electronics in the camera picking up the signals I believe. I have no clue how much power came off that building but in the year 2000 I could get stations broadcast from it in Connecticut with rabbit ears.
Ah old school rabbit ears antennas! Funny story in a way but was yet practical. Anyone that still has rabbit ears antennas should keep them sometimes they're actually better for digital than you think they might be sometimes I've gotten better reception with a pair of rabbit ears instead of modern flat antenna in any configuration. I remember one place I stayed years ago I was trying to get the best digital TV reception when I moved in! So what I did is I guess you could call it a site survey for best antenna placements and configuration! Put a long coax cable after using matching Transformer on antenna of course. And there was a sweet spot almost in the middle of the place however that was between kitchen and hallway so no go. But as went around I noticed that if things tended to get good better almost the greatest but not quite as I got closer to the outside door however even better was in top of the front closet above a metal Shelf system. I'm wound running coax underneath the door plenty of space so when may damage plus was covered in Split Loom and spiral wrap in some places. Also ran speaker wire and a chopped up USB extension. You might think digital TV amplifier but no. Actually closet light!!! Already had a way to get the cable there so why not you almost couldn't even see inside the closet so it did help. Unfortunately was running so couldn't exactly girl through the wall or Mount anything permanently did try using the original antenna system sometimes works but no dice. Apparently there was an old Community antenna system AKA Central antenna somewhere there was coax everywhere and to coax ports probably one was added later possibly I know that at least one of them was for cable TV and the other was antenna! All the information about it was in the paperwork but no one knew anything about it other than that so who knows how long ago that that was not working in terms of the antenna for the place! It was clearly some newer coax since you can see it running in various places in the apartments in the surface and then going back into the wall and most of those box covers or plates were used to cover up the oopsies or just holes or newer than the rest to be fair most of the older coax plates were painted over with the exception of the ones used for cable TV
Really enjoyed that Lewis. Its the sort of thing I've been doing for many years. Military sites are a curiosity to me mainly. But any antenna and I want to have a look.
Thanks, Lewis this is most interesting. I never visited the mast but I remember when it opened as a TV transmitter. It was a bit thing those days as this was the third TV station in England and a special program went to air. Where I lived as I do now we picked up TV from the Hints transmitter near Sutton Coldfield. would love you to cover this. Thanks, Robert...
Excellent video Lewis. Love antennas and learning what they do. Very interested to see the differences between UK broadcast towers and Aussie ones. Keep up the good work!
that corrugated metal structure could be a shelter for elevator equipment (motors and control systems). Some of those taller towers have personnel elevators built in the interior of the tower.
Great video Lewis! Please visit more broadcast sites like this as they are really interesting. There are also some aircraft comms sites around Manchester Airport and Manchester City airfield that are worth a visit.
@@RingwayManchester I don't know the addresses off the top of my head but some include opposite the flying horse pub M22 5LT and Hobcroft Lane WA16 7QR. More can be seen on satellite View.
I stay within minutes of 3 major masts and stations and a microwave backbone site. They have always fascinated me. After learning more about the backbone network from your channel and studying the tower it’s become a shadow of its former self. There is hardly a dish on it now, it looked like a giant minion when I was younger with its two giant microwave dishes!! There was also an MOD site with a tower too but that was rubbed out a few years ago, and returned to nature. How technology moves on.
Thoroughly enjoyed🎉 something more technical and interesting. Beats the pirate radio stuff hands down. Maybe you would consider doing similar for different types of masts.
My brother worked for Alan Dick on these towers. Then he was a contractor and worked all over the world and also for Arquiva. He also worked on cellular antenna design for Alan Dick. He used to take great photos from the towers. Sometimes he would come down the guy wires too. He did that on a job in Brunei and got great jungle photos.
Love your informative videos, and think its wonderful thst you can discuss what the equipmemt does rather thsn just show random pictures , while talkimg about this numbers station or thst oddity
I don't even live in the same hemisphere as this transmitter array, but I still watched the whole thing, because nobody ever explains what all this crap is for.
Unlike some commenters I enjoy your other content a great deal - but I also enjoyed this video a lot! Even details you probably wouldn't consider - I live in Florida and "falling ice" isn't something I ever would have considered!
Paul, Look up what happened to the first tower at Elmley Moor - I'd suggest covering it but there's already a few videos out there so I don't know if it's a priority job.
I build GEO satellites so it’s cool to see the contrast between small space grade RF equipment and very large scale radio infrastructure. I’d love to see more of this! I’d also like to see the physical transmission infrastructure from the ground, to and up the the tower if possible
Check out eevblog - he's got a video of a TV transmitter in Sydney Australia. You get to see it's innards plus some extra stuff inside the building including some newer solid state transmitters.
Satellites are always amazing stuff, But it must be some serious launch day butt pucker when the countdown on the live stream hits 0. Because once that rocket is released its going somewhere, and hopefully pointy end up. With rockets sometimes launching weekly, its so easy to forget just how many moving parts have to cooperate so a satellite lots of people spent years building goes to space rather than to the alligators living at the space center in Florida in very small pieces.
Please do more of this material, I'm an antenna geek and always looking up when out and about to see what wire or metal is in the air :) It's fascinating to see what is used in all of these varied comm's links. 73 G7KDM :)
There's a large microwave network in Europe and this site is I think one of the locations connecting to it. What is transmitted over the Microwave networks is unknown. Ars Technica has a article on this network called "The secret world of microwave networks".
hAMS used rather large horizontal antennas where the aluminum tubes go crossways and parallel to the earth. Those towers there are only straight up with nothing on top are usually transmit-only antennas for entertainment programming either radio or TV.
Very interesting video - thanks for posting. I did find all the defocus transitions a bit distracting but it was fascinating content all the same. Thanks!
I've hung a few of these in my day elsewhere. I wrote up a large comment on what stuff probably was, then started listening to you and you were really really close to being perfectly spot on so erased it. 5:56 I think that dark gray radio might actually be an internet access point for whatever reason (edit - i think its 900mhz if memory serves but ill check what i have if you reply asking me too) and they just decided to use the existing standoff arm instead of adding a new mounting arm. I suspect that it is being fed off one of the ubiquity internet radios because I only see 1 cable feed running into it (and its shadow), and no RRU, and I've got a few identical too it in my garage. 9:19 I can tell you likely know this already but those are fiberglass panels because it doesn't interfere with RF, and I'd wager once upon a time a cellular carrier was there, I've seen this exact approach in the past to shield the stuff from sheer force damages where you need something basically pressure rated to withstand the rain+wind forces that the equipment isn't rated for, saving BIG bucks by not needing specialized housings to keep hurricane gusts from pushing water into the radios by force. From what I can see, there are no indicators anything is behind them. I do see 2 electrical conduits running past it, so we cant completely rule out that there isn't something up there that doesn't need ground wires and its just a hidden relay that only needs AC to operate with the job of taking a signal from one side, and sending it out to another dish(s) with it's own self contained systems up top so no need for a ground interface and It might just basically be a tucked away OSPF relay; who knows. The only issue I see is if its not in use, then it's a ton of unnecessary wind loading at the top, and it really should be taken down. I'm very curious now what you do for a living. ~Cheers

there before 9/11 in October 1981. Also
been to the antenna site at West Peak near
Meriden, Connecticut, for some of the FM Hartford CT area stations, at over 1000 feet
above sea level, and finally the antenna site for Montreal Quebec, on Mont Royal site, above the city in 2008. Ray W2CH.
I remember being on the observation deck of the World Trade Center long ago, and I was amazed at how big that radio mast was on the opposite tower.
@@RCAvhstape another big array is the one on sears tower chicago.
@@RCAvhstape I once saw WNYW Ch. 5 from the WTC, at my house 1000 miles away, during strong skip. It was a year or so before the towers fell.
A friend (a former GPO/BT tech based at Telco Tower London) says that the Mini Tower at Heaton Park was part of the Backbone and Secondary for broadcast. Perhaps you might look into this. Great content, you can of course assume more content like this, would be most welcome.
This was an interesting video of this transmitter site. Brilliant work. I am an Armature Radio operator in the U. S. Always nice to see other transmitting equipment in different parts of the world.
Great episode! Yes, please more of this type of content!
I’m in the U.S. , but I really enjoy your channel, and this episode is definitely one I found very interesting!
Thanks for the great work you do and the extremely interesting content!!
Whomever it was that designed and constructed the anchoring did a damn fine job of it, and whomever performs the structural maintenance also "means business", as evidenced by the thoroughness of the application of the gunship grey paint, and the fact that absolutely no rust is visible, nor are any other signs of corrosion evident. At those heights/'altitudes', actually, one often sees streaks of rust, or other signs of corrosion, and that tower is pristine! Cheers!, and thanks for the upload!
Yes, when I worked there, the mast was painted I think about every 6 or 7 years. They used to use the same paint as on the Forth Rail Bridge, but these days it may be an epoxy based one. I remember at another site, we had 6 tons of paint delivered to put 3 coats on 4 tall towers. I was told that only about 1.5 tons would remain on the metalwork, the rest was solvent which would evaporate into the atmosphere! The paint is water-based these days so most of what evaporates is just H2O. When these masts are painted, the staff have to park their cars away from the building, otherwise they are likely to get spattered with paint that is impossible to remove without damaging the car's finish. (I know from experience!) The paint has a careful amount of thinner added to make it easier to apply, but not too much to cause the coat to be too thin. This is checked by microscope to make sure adequate thickness is applied. Painting is one of the more dangerous maintenance jobs because they have to get to all the nooks and crannies of the steelwork. This involves swinging down on bosun's chairs with a kettle of paint hanging from their belt and a long-handled brush in hand. Naturally, the adjacent antennas are powered down while they are working. I remember one painter asked if a large 1.5m diameter microwave dish was powered off for him to work in front of. He took some convincing that it was used for receive only and so the power was in the nanowatts or less! The guys or stay wires are regularly greased as well to prevent corrosion. Luckily, Holme Moss is well inland, probably 100 miles from the sea, so salt water corrosion is not a problem. Some transmittere sites near the coast are not that lucky.
I remember jumping off Winter Hill attached to a hang glider in the late 80s. It was mostly foggy on and off.
To see Holme Moss defying the elements on a bleak day is a wonderful sight to behold. Loved this and your pirate radio videos. More please. I love broadcast related stuff like this. 😁
I have to agree, the fact that such a massive, and probably very heavy bit of kit can stand there and not blow over, makes it just as impressive as the aerials!
anybody know how much the structure weighs?…
Amazing rog! This is why you are my goto when I see an antenna and want to know what it is!
Fascinating - I work in telecoms so recognise some of the cellular and microwave links, I also had a stint doing student radio at uni so dabbled with a short range microwave link and the associated FM transmitter, but all of this gear is on another level - I'd hate to have to climb that mast though :D
I very much enjoyed this video. Please do more. I went to a local mast @ West Hoathley which carried all sorts of strange antennas including TETRA , took some pictures and the police were called! Have you ever tried explaining yourself to a brain dead non technical police woman who thinks Facebook has its own aerials? I have!
Absolutely love this type of content. Keep up the great work :)
Awesome video Lewis! Definitely like to see more antenna arrays.
Really enjoyed looking at this amazing structure.
Interesting to see the damage inflicted by a wayward ice chunk on that microwave antenna.
Great Video Lewis. Thanks. I can confirm the necessity of the shelter having been stuck near the top of a tower crane during a sudden thunderstorm. Hanging on for dear life in freezing rain and high winds is not fun.
Yes sir I’m in America and I think this is very informative so go for it
Great video - went up there yesterday (fantastic weather but icy!) and really appreciate the rundown of the equipment and purposes.
That's one very busy mast! So much good content in this video. I can't imagine how long it took to compile it. Well done, sir!
Haskell - W5HLM New Braunfels, Texas
Plenty going on up on thoughs masts.
Such a variety indeed.
Towards the end I was getting the feeling of vertigo!
Thanks for the info Lewis 🙂👍
Another quality video Lewis and explanation of different antennas,look forward to more of these videos thank you.
Great video Lewis! When you are in Holmfirth they say if you can’t see the mast then you know it’s raining. If you can see it you know it will start raining soon 😂
I have some photos you might like I took from one of the Arqiva auctions where I brought quite a few of the TXs recently used as part of the switch over project, and we had to remove them from the racks ourselves. So lots of RF kit.
I now have a spare room full of TXs from Emley Moor and not exactly sure why I grabbed them but seemed too good an opportunity to let them pass 🤣.
Would love to see pics Adam! Ringwaymanchester@mail.com
Love the geeky side of anything electrical, keep 'em coming!
Has been something I've seen as long as I can remember living in South Manchester
Really interesting Lewis thanks for sharing and plese keep the intesting content coming 👍
Most of the info went over my head but I still found it really interesting, thanks Lewis! Hmm, the corrugated section, perhaps some secret military surveillance antennas? 😊
NOT long winded at ALL! Very interesting and great detail! Thank you.
That's a lot of antennas to maintain. Imagine the disruption if that tower came down unexpectedly.
👳🏾♂️
I find this kind of content - giving us new eyes for the things around us - very satisfying to watch. Subscribed.
Excellent video Lewis 😀 . It reminds me of when I used watch BBC and IBA Engineering broadcasts to the trade in the 1980s when off school . Always fascinating stuff - thanks.
Iba broadcast
Yeah tuesdays ch 4 if i remember
Remember them well. That monotone voice telling us that winter hill will be on low power this afternoon on all services while brierley hill will be qrp for fm services only. Lol.
@@vw663 Yes, better than watching Test Card F all morning. The IBA Archive on UA-cam brings back memories of these broadcasts.
@@lukedavid4393 Thanks @Luke David, wasn’t aware. I’ll take a look. 😀
Fantastic level of detail. Certainly a lot on one mast. Yes, absolutely, more of this type of stuff please.

I'd love to see a video on the RBS structure and maybe incorporate the RBS test!
Love your work making broadcast technology accessible and understandable.
Videos like this are awesome, not long winded at all! For those of us not in the UK, maybe a video explaining how all the networks work together? You were using another name for a network I have no idea what it was, sounded like a company name. Does everywhere get BBC 1,2,3, etc but only Wales get the BBC Wales station? Those kinds of things.
Short version is that the entire UK gets the "national services", which consist of BBC R1, 2, 3 & 4 (on FM), plus 5 on MW and a few extras on DAB. These are transmitted from sites all over the UK, which are fed from London via a NICAM link. In addition, the UK is divided into "regions" with their own "local radio" station, BBC Essex, Southern Counties, or whatever. These are usually only transmitted from one or two sites to cover the smaller area.
Like others have said. Thank you for making these videos, I can now bore my passengers as I drive past these antennas. I would love to see whats inside the cabins around the base of these aerials, hopfully someone might be able to get you inside.
Good vid. Prefer this over a seemingly endless stream of pirate radio vids... Breaks things up is why.
I agree variety is good, I tend to enjoy it all.
noooooo!
I really loved this video. I've often wondered how the TV broadcast and radio broadcast done in the UK. I use to live there at RAF Bentwaters in the early 1990's.
Brilliant video Lewis, very interesting and informative. I had the opportunity to go up the Mendip Mast (Pen Hill, Somerset) near me many years ago and was fascinated by all the equipment, would love to visit more of these installations.
Even though I’m “across the pond” in the USA, I’m very interested in any video you post. Doesn’t matter the subject. I especially like any commercial equipment along with Amateur Radio as I’m a ham too. (N6FRW). Thanks for all your videos.
The "Falling Ice" sign made me laugh. I visited NYC in 2016 and experienced 26" snowfall. A walk near any of the high rises bore risk and I saw 2 foot icicles crash to the pavement in front of me. Avoiding them became just another NYC skill.
Most interesting video of late Lewis
Very interesting - yes please do make more! The thing at the top of the mast, I think is a radar reflector, for aircraft.
Really nice video on what all these antennas do. Really, I thought it was like a two minute video when in fact it was 10 minutes, very informative very interesting thank you.
SIMPLY OUTSTANDING I love them and only know the basics so get a grasp of some the other shapes we sup there is super. Great footage.
Nicely done aa usual! You must put a lot of time into research and I'm sure your fans here are as grateful as me.
Really interesting video. Had no idea there were so many different services on one tower.
Have you made any videos about how all of the services are managed at one site ? Or is that impossible due to security etc. ?
Great episode 👍
Always a great video. I love this type of content.
if you ever wonder about how much EM can come off the primary transmission elements, I once saw a documentary where the crew was way up on top of Empire State in NYC right below its transmitter mast and you could see the wavering in the video from the electronics in the camera picking up the signals I believe. I have no clue how much power came off that building but in the year 2000 I could get stations broadcast from it in Connecticut with rabbit ears.
Ah old school rabbit ears antennas!
Funny story in a way but was yet practical.
Anyone that still has rabbit ears antennas should keep them sometimes they're actually better for digital than you think they might be sometimes I've gotten better reception with a pair of rabbit ears instead of modern flat antenna in any configuration.
I remember one place I stayed years ago I was trying to get the best digital TV reception when I moved in!
So what I did is I guess you could call it a site survey for best antenna placements and configuration!
Put a long coax cable after using matching Transformer on antenna of course.
And there was a sweet spot almost in the middle of the place however that was between kitchen and hallway so no go.
But as went around I noticed that if things tended to get good better almost the greatest but not quite as I got closer to the outside door however even better was in top of the front closet above a metal Shelf system.
I'm wound running coax underneath the door plenty of space so when may damage plus was covered in Split Loom and spiral wrap in some places.
Also ran speaker wire and a chopped up USB extension.
You might think digital TV amplifier but no.
Actually closet light!!!
Already had a way to get the cable there so why not you almost couldn't even see inside the closet so it did help.
Unfortunately was running so couldn't exactly girl through the wall or Mount anything permanently did try using the original antenna system sometimes works but no dice.
Apparently there was an old Community antenna system AKA Central antenna somewhere there was coax everywhere and to coax ports probably one was added later possibly I know that at least one of them was for cable TV and the other was antenna!
All the information about it was in the paperwork but no one knew anything about it other than that so who knows how long ago that that was not working in terms of the antenna for the place!
It was clearly some newer coax since you can see it running in various places in the apartments in the surface and then going back into the wall and most of those box covers or plates were used to cover up the oopsies or just holes or newer than the rest to be fair most of the older coax plates were painted over with the exception of the ones used for cable TV
I spend way too much time guessing what is on towers when I drive by. Fun to guess by antenna
Really enjoyed that Lewis. Its the sort of thing I've been doing for many years.
Military sites are a curiosity to me mainly. But any antenna and I want to have a look.
Thanks, Lewis this is most interesting. I never visited the mast but I remember when it opened as a TV transmitter. It was a bit thing those days as this was the third TV station in England and a special program went to air.
Where I lived as I do now we picked up TV from the Hints transmitter near Sutton Coldfield. would love you to cover this. Thanks, Robert...
Interesting to learn about the aerials up the mast. I like learning about microwave transmission. More please when time allows.
That tower is a monument to a lot of very smart people!
Excellent video Lewis. Love antennas and learning what they do. Very interested to see the differences between UK broadcast towers and Aussie ones. Keep up the good work!
Thanks mate!!
You should ask around and see if you can get a tour of the rf equipment inside the buildings. Would be cool to see.
that corrugated metal structure could be a shelter for elevator equipment (motors and control systems). Some of those taller towers have personnel elevators built in the interior of the tower.
Great video Lewis!
Please visit more broadcast sites like this as they are really interesting.
There are also some aircraft comms sites around Manchester Airport and Manchester City airfield that are worth a visit.
Hey mate let me know where they are.
@@RingwayManchester I don't know the addresses off the top of my head but some include opposite the flying horse pub M22 5LT and Hobcroft Lane WA16 7QR.
More can be seen on satellite View.
Are you sure? Cause I did some research on all these sites and all of them were gone.
Very informative yet again Lewis. Definitely one of my favourite channels.
I stay within minutes of 3 major masts and stations and a microwave backbone site. They have always fascinated me. After learning more about the backbone network from your channel and studying the tower it’s become a shadow of its former self. There is hardly a dish on it now, it looked like a giant minion when I was younger with its two giant microwave dishes!! There was also an MOD site with a tower too but that was rubbed out a few years ago, and returned to nature. How technology moves on.
Scary what has replaced it.
Constant structural analysis is necessary for every addition to the Tower, including icing. The wind loads must be enormous
Yes, more content like this please. It’s fascinating
Very interesting would like to see one about winters Hill
Long winded? Nope, that 10 mins flew by!
Mate you are the Tom Scott of radio comms info!
I had no idea I was interested in antennas until I watched this video! Thanks mate 😉
Thoroughly enjoyed🎉 something more technical and interesting. Beats the pirate radio stuff hands down. Maybe you would consider doing similar for different types of masts.
Am sure we used to drive to one, near Sheffield passed snakes pass , I was young back then the driver dave said they was TV but its beyond me
Very interesting, thanks. You should write a Kindle book on Antenna Spotting 😁
My brother worked for Alan Dick on these towers. Then he was a contractor and worked all over the world and also for Arquiva. He also worked on cellular antenna design for Alan Dick. He used to take great photos from the towers. Sometimes he would come down the guy wires too. He did that on a job in Brunei and got great jungle photos.
Excellent content thanks for sharing your thoughts 👍I am a aerial rigger so I understand everything you went through.
Love your informative videos, and think its wonderful thst you can discuss what the equipmemt does rather thsn just show random pictures , while talkimg about this numbers station or thst oddity
I don't even live in the same hemisphere as this transmitter array, but I still watched the whole thing, because nobody ever explains what all this crap is for.
You follow my line of thinking. Very enjoyable and very informative, 2nd viewing now to catch the detail. PS love all of your output. Thank you
Unlike some commenters I enjoy your other content a great deal - but I also enjoyed this video a lot! Even details you probably wouldn't consider - I live in Florida and "falling ice" isn't something I ever would have considered!
Paul, Look up what happened to the first tower at Elmley Moor - I'd suggest covering it but there's already a few videos out there so I don't know if it's a priority job.
I build GEO satellites so it’s cool to see the contrast between small space grade RF equipment and very large scale radio infrastructure. I’d love to see more of this! I’d also like to see the physical transmission infrastructure from the ground, to and up the the tower if possible
Check out eevblog - he's got a video of a TV transmitter in Sydney Australia. You get to see it's innards plus some extra stuff inside the building including some newer solid state transmitters.
Satellites are always amazing stuff, But it must be some serious launch day butt pucker when the countdown on the live stream hits 0. Because once that rocket is released its going somewhere, and hopefully pointy end up. With rockets sometimes launching weekly, its so easy to forget just how many moving parts have to cooperate so a satellite lots of people spent years building goes to space rather than to the alligators living at the space center in Florida in very small pieces.
Great video, as are the pirate radio ones. Extra good viewing lately. Cheers Lewis.
Despite all the mobile services on the mast, coverage is very poor up there. Probably in the shadow below what the antennas can see.
Please do more of this material, I'm an antenna geek and always looking up when out and about to see what wire or metal is in the air :) It's fascinating to see what is used in all of these varied comm's links. 73 G7KDM :)
There's a large microwave network in Europe and this site is I think one of the locations connecting to it. What is transmitted over the Microwave networks is unknown. Ars Technica has a article on this network called "The secret world of microwave networks".
Wow, very complex system. Must be fun chasing out intermod.
hAMS used rather large horizontal antennas where the aluminum tubes go crossways and parallel to the earth. Those towers there are only straight up with nothing on top are usually transmit-only antennas for entertainment programming either radio or TV.
Very interesting and informative... more videos like this would be greatly appreciated.
Great video! Really enjoyed it. Would love to see more of it; also in different countries (like the Turkey episode). 73
Thank you, Lewis. Very interesting. M3TDZ
Good video, I live fairly local Barnsley actually, always wondered what all the bits were.😁
Very interesting video - thanks for posting. I did find all the defocus transitions a bit distracting but it was fascinating content all the same. Thanks!
Antenna systems and their inherent engineering is a fascinating science.
Very interesting Lewis as always. More of the same please. Love it
The shelter is a bolt hole for climbers to get out of the wind and weather whilst working on the structure.
I've hung a few of these in my day elsewhere. I wrote up a large comment on what stuff probably was, then started listening to you and you were really really close to being perfectly spot on so erased it. 5:56 I think that dark gray radio might actually be an internet access point for whatever reason (edit - i think its 900mhz if memory serves but ill check what i have if you reply asking me too) and they just decided to use the existing standoff arm instead of adding a new mounting arm. I suspect that it is being fed off one of the ubiquity internet radios because I only see 1 cable feed running into it (and its shadow), and no RRU, and I've got a few identical too it in my garage. 9:19 I can tell you likely know this already but those are fiberglass panels because it doesn't interfere with RF, and I'd wager once upon a time a cellular carrier was there, I've seen this exact approach in the past to shield the stuff from sheer force damages where you need something basically pressure rated to withstand the rain+wind forces that the equipment isn't rated for, saving BIG bucks by not needing specialized housings to keep hurricane gusts from pushing water into the radios by force. From what I can see, there are no indicators anything is behind them. I do see 2 electrical conduits running past it, so we cant completely rule out that there isn't something up there that doesn't need ground wires and its just a hidden relay that only needs AC to operate with the job of taking a signal from one side, and sending it out to another dish(s) with it's own self contained systems up top so no need for a ground interface and It might just basically be a tucked away OSPF relay; who knows. The only issue I see is if its not in use, then it's a ton of unnecessary wind loading at the top, and it really should be taken down. I'm very curious now what you do for a living. ~Cheers
Really informative video and reaches out to more people as we all see these site and wonder what’s what.
