I am an amateur radio operator. We lost our 3.3 to 3.5 gig allocation as well
No hams really used it. I think maybe ARERN had a few but other than that, I don't know anyone who used it. Equipment not cheap like the 2.4/5GHz gear. Even 900MHz is more viable.
We just went through this last month where it took 3 days of dish tweaking, high winds on a 4-story roof in West L.A., and lots of "stuff" on top of the PRSS signal showing up on the Anritsu.
A new 5G-filtering LNB, and lots of tweaking the dish up, down, and sideways 1/32" inch at a time, and we finally got a stable signal, though it wouldn't take a lot to lose it.
I was one of these, unfortunately I don't live in FCC land and nor did I find out about it until it started happening. We had to scour the internet for a filter that was compatible with our huge dishes. (In rural, nowhere, as 5G cell sites were being fired up.)
One thing I'll give 5G, all of the neglected (populated) communities are now getting decent coverage. I'm sure a lot of people here don't remember any recent time where they couldn't send an SMS; I worked for a company that served these areas (and boy was it annoying not being able to use data or send an SMS message here)
Talking about 5G and satellite TV interference: there was an interference issue here in Mexico (I live in Mexico), exactly in Ciudad Juárez across El Paso where the Imagen Television repeater there was having interference from cell phone companies. People was thinking it was caused by Telcel (a mexican company) but after doing some research it was discovered that the interference was being generated by Verizon, but since Imagen didn't use filters at the moment, well, the problem was very notorious. Imagen uses the Galaxy 19 satellite at 97°W in a transponder with a frequency of 3.913 GHz, and Verizon was using a closer frequency and that was causing the problem.
when you said mhz did you mean gigahertz? that would be shortwave and have a huge satellite dish.
Maybe... what was the timestamp I said that? With satellite, we typically talk in MHz. So 11450 MHz for a KU downlink instead of 11.4 GHz. Maybe I said 11.4 MHz instead of GHz. Oops.
@@TheBroadcastEngineer Yep. @12:00, you said C-band was 3 - 6 MHz and Ku was 11 - 14 MHz. I realised you meant GHz.
@patrickmitchell6968 Oops! Yes, GHz. When we use it we do it in MHz as in 4000 MHz or 11750 MHz.
The frq's will cross the infrared bands in the next cellphone networks, older phones had it already lol
The cell tech that you're referring to is UWB ultra wide band, which isn't below (depending on license holder) c-band. The wireless carriers and Satellites are kinda amongst each other within the cband range. I didn't get into the regulatory changes as far as spacing but they're probably stomping all over each other... Also in that range are older radar altimeters, about a year ago I think it was, carriers(I believe ATT mobility was the big issue) had to turn down sites near airports if they were within a certain radius until retrofits or parking of planes happened...
5G is a nearly meaningless term compared to 4G for instance. 4G was pretty much just LTE on the old analog TV spectrum. 5G started as basic as better radios that used the same spectrum more efficiency, to new Frequencies like UWB and mm wave which is 24 to 53 Ghz... It's a marketing term
The mm wave stuff is small cell type deployments that will take a long time, plus a big bottleneck is upgrading cell site backhaul. Some sites, not hubs or anything are getting 125gig DWDM fiber.
If I recall, 4G is sub 6GHz. 5G is now including mmwave, which is a huge difference worth mentioning.
Does it make me insane for having just installed a 10 foot c-band dish? I'll be getting a bandpass LNB soon enough.
Not if you’re taking content off of it.
@@TheBroadcastEngineer That's certainly the plan. Am holding out for an all in one package to avoid having to buy 1-2 waveguide filters, though.
@@TheBroadcastEngineer Well, I have to get a mover...and maybe give some TLC to the 20? 30? year old actuator but it currently is even getting 4k NASA from 127W
Are there still data and a few video channels available in the top of the old 3.7 to 4.2Ghz (? to 4.2Ghz)
or another way to ask my question is there still data and a few TV video channels BELOW 4.2Ghz ?
Thanks for all of your videos and like everyone else we miss the Santiago Peak feed. It was like being
on Santiago Peak but without beating up me and my truck.
Video as in terrestrialy delivered or by satellite?
Because with satellite it’s still very very active on C Band.
I hear you about the Santiago Peak feed. I wish they could have kept it up but if you go to Airsites2000.com they have some as well as HPWREN (better quality).
@@TheBroadcastEngineer Satellite and I will do a little research on programing. Thanks
@@TheBroadcastEngineer I think we are all sentimental over Santiago peak. Thanks for the link !
@@TheBroadcastEngineer Does the FTA
C Band satellite digital format TV the same as the FTA celestial digital TV format ? Thanks
us consumers of Free TV were ignored. 5G is mostly Hype
Where you referenced MHz, you mean GHz right?
More than likely. I went off script and was using an outline instead of a teleprompter script.
5G towers also interferes with over the air Free UHF TV also.
Sorry, off-topic question. Do you remember which of your videos you showed what an Educational Media Foundation rack looks like? You know, the one where they install LEDs around the back of the rack so you can see the back side of the equipment rack without having to bring a flashlight in?
That would have been one up at Arden outside of Las Vegas. I’ll have to look.
I’m not finding it either… strange.
What is 5G have to do? Your English suffers.
What are you talking about?
