Hi Tim, I’ve had one of the Steve Webb originals for quite a few years now and been very happy. It does sit on a crank up mast so I manage to get it up to 35 foot. When not in use it just sits above the ridge of the roof, not very visible to the neighbours. Highly recommended. Thanks for the vid 👍🏻👍🏻👍🏻
Very good Tim! Interesting type of antenna, with lots to recommend it ,small footprint, resonant multi element with no rotator required and pretty easy to make your own! I've read lots of reports suggesting they work well without having to be at great heights, It would be interesting to do A/B testing with two identical Cobwebs at different heights. 73, Tom
Great info on the antenna, Tim. Congrats on the move in to the new shack. Looks a lot warmer that the shed! I can't wait to see it fully decked out. Keep the videos coming and thanks for making them. 73's De Syd EI3IEB
Another tip is to make sure the element end joining cord is not water absorbent as apparently this can affect the SWR in the wet. Thanks for the video Tim 👍🏻
Food for thought there Tim, thanks for the video. Massive congratulations on your Subscriber count my friend. I remember you reaching 400 for goodness sake. 👍🏽
I have had a Cobwedd up for around two years now. My is the the MFJ -1835. It took a but of reworking when I bought it (new from a local emporium). It is the single wire version. I have since re-strung it with good quality wire and paracord. It is now great and resonant on most/all parts of all the bands. 73
Great video, yes I have one and it is (was) the best omnidirectional antenna. Where there is a lot of light there is also shadow. 1. Very narrow band. 2. extremely sensitive to moisture and 3. very sensitive to a lot of snow. Mine was totally destroyed this year and the elements were completely pushed down. And now I'm thinking about whether I should buy or build one again.
Just revisited this vid as am thinking about constructing a Cobweb myself. Interesting comments about characteristics during precipitation. Whilst can't predict the performance of the antenna, I can predict the critique from my wife as I erect another blot on the landscape... Anyway, it was good to hear your comments
Hi Tim. I have to assume all is well on the C19 front and no worries. Nice looking shack and I bet it will look really great when you have fully moved in. I cant really get HF at my QTH simply because I have a really small garden and a overly cautious XYL HiHi and even a glorified cloths lines is out of the question. Thanks for sharing and Im sure there will be those who will give this antenna a consideration. 73

Hi Tim ! Glad to see you are well and thanks for another fantastic video. I was wondering with your new 'shack' you could do something on cable management/keeping cables tidy. For a computer this is straightforward, but with a transceiver, computers and all the other wires/connectors, would love to know a good way to keep things tidy and safe/working for radio use. My shack is amess of cables and i cant find a good video on amateur radio cable management anywhere !
Hi Tim, some great videos you have here on UA-cam, I am looking at a multi band cobweb but it would need to be mounted in the loft, is this possible do you think or would I be better off using and EFHW sloper, I am in quite a restricted area so as stealth as possible or loft mounted Thanks
A cobwebb is 8 feet square so you will need a decent attic in terms of space as you will need a good few feet of clearance from the antenna. I have seen a few designs for fan dipoles in attics - you can zig zag to fit in 40m for instance. OR you can feed as big a dipole as you can fit with ladderline to an atu via a 1:1 or 4:1 BALUN and multiband that way. Hope that helps.
Hi Tim. Great video put out just when I was thinking of making one. Out of interest, as I am very limited getting any height to an antenna, if this was 4m high would it show some NVIS characteristics? Look forward to seeing the finished shack. 73. Liam GM4VYQ
Hi Liam like any dipole the nearer to a Halfwave in height the lower your take off angle (unless you go appreciably higher than half wave in height which can cause Nulls as well as lobes). At 4m you are nearly a Halfwave on 10m. You’ll still make contacts and occasional DX at that height even at 20m. 73
Hi Tim,would the cobweb antenna at 35ft beat a hustler ground mounted vertical for dx?? Hustler works great but want better and no room for a hexbeam as already tried that.cheers
Verticals need good ground systems or be close to saltwater to excel. Try between 16 and 32 radials as short or as long as you can get them, more short ones are better than a few long ones. You may notice your SWR goes up, this is down to ground losses being reduced as the efficiency is improved. It also depends on the bands you want to work. I have a Cobweb at 35 feet and If I can hear a station, I work them. I also use verticals close to or over saltwater, they are superb performers then. If you can't get close to the sea, this is how a 1/4 wave plays over a VERY good ground system, 100 plus radials. ua-cam.com/video/EWCTP5-lK3Y/v-deo.html
@@timg5tm941 cheers guys but had both up now for few months and must admit the cobwebb out performs the vertical 99% of the time and ALOT less noise :) am using around 280 meters of radials on the hustler and am about 1 mile as the crow flies from the beach.bith performing very well BUT cobwebb swr changes ALOT in the wet
@@timg5tm941 That is why I needed? the actual required length so when I add to the ends it will be enough, thinking of adding some wooden dowls covered by a small pvc pipe, if it is just a few feet?
Steve Webb is my grandad. He doesn't talk to me about it really and only heard about the cobwebb from my mum who used to do the soldering.

Sure you’ll soon have that new space filled up with gear 😉👏👏
Hi Tim, I’ve had one of the Steve Webb originals for about half year now and been very happy, particularly with the 30 & 40mtr add-on.
Hi Collin could you tell me where you purchased your add on kit or did you make it yourself ? warm regards Mike

Twin wire is the best
I like the cobweb design. I live in a hollow, so take off is limited and do not want knitting all over. A little height with this would be nice.
Very good antenna for its size certainly
Excellent video!!!
