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!

Really interesting info thank you!

[@m0wms]

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.

[@peterlee2622]

@@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.

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.

[@DARTHDANSAN]

Fascinating info such a huge antenna

[@TomStorey96]

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.

[@gregjones3660]

Risk vs reward…

[@nickwallette6201]

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.

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.

[@aaronbrandenburg2441]

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

Those combiners seem to be a fascinating subject. New to the channel so not sure if they've been covered but might make for an interesting video as well. And speaking of relic antennas, I'm from Australia where we still have a lot of homes with what I assume are defunct satellite TV dishes - rusted and crusty, yet still clinging on for some reason. They used to be a status symbol in the 90s and early 2000s, maybe that's it lol

[@onesandzeros]

Agreed about the combiners. They're hollow I think and their internal volume is adjustable to allow tuning, and it's just electromagnetic wave in there. eevblog has an interesting video which is a tour of TV broadcast facility in Sydney if I recall correctly, some equipment was being retired due to conversion to digital TV. One section of the building has some waveguide, very interesting.

[@arjovenzia]

In some parts of Australia, you can receive satellite feeds intended for South Asia, and the Middle East (with a sufficiently big dish). Most of the large dishes are for this, so immigrants can get TV from "the ol country". My house had one when I bought it, I was hoping it would come with the place, but the Pakistani bloke said the system cost over $10k, so was coming with them. Still, the 6in post n 1m^3 of concrete made a fine base for my ham mast. That was 6 years ago, so was definitely in use then and there was a place that sold such systems near where I worked 2 years ago, n they seemed to be doing OK. I had to get the internet wired in when I moved in, so there's definitely people who still use that over the internet.

@@arjovenzia big dishes used to be an in thing in the USA ages ago. 1m sometimes bigger C-Band and you had to point them at the right bird, Once things like DirectTV took off they started to die out.

[@peterlee2622]

Those combiners are a real engineering artwork. Unlike in many parts of the world, in the UK we commonly combine together 4 or 5 high power transmitters into a common antenna. They consist of typically 2 x 3dB couplers and 2 resonant cavity filters (at VHF the size of dustbins) per frequency, arranged in a string, with each service being combined into the final signal going to the antenna as you go along the string. Incidentally, the coax that is used is around 150mm (6 inch) diameter or more and in the building consists of aluminium pipes with copper inner conductors held by PTFE insulators. The coax running up the mast is a similar diameter but uses corrugated copper outer and inner conductors to give it flexibility and ability to bend somewhat. It is very expensive and very heavy! Oh, and all this is usually duplicated on main stations like Holme Moss. There are 2 transmitters for each service which each operate into half the antenna system. In normal operation, both transmitters operate together, but if there is a fault, one side will continue to provide a usable service at one quarter of the usual ERP. (Half transmitter power, half antenna aperture.) Of course, the 2 transmitters have to be fed from the same drive source and in phase. Wrong phasing happened when Radio 1 VHF was powered up at Holme Moss for the first time. Someone got the wrong cable lengths and remote signal strength dropped when the parallel transmitter was turned on! A quick 180 degree length of coax on one of the drive outputs cured the problem!

[@Technaudio]

Since it's clear that you know far more about radio waves than me, I would like to ask a question that I have wondered about for quite some time; My [very limited] understanding is that radio waves are the lower end of the electromagnetic spectrum, which also includes visible, infra red & ultra violet light, X-Rays & many other things. I also understand that this is a way astronomers use of measuring distance of very far away light sources and whether they are moving towards or away from us - (red shift & blue shift), waves that have been travelling for a very long time? These light waves eventually stretch or compress so much that they no longer are visible, and subsequently become radio waves that can be picked up by other means? So, going back to the low end, and radio. If I were to have a radio transmitter tuned to a certain frequency, and I was to talk into that radio set, If there was nothing tuned too that frequency at the time I transmitted it, (I assume this is highly unlikely?) what happens to that? Does it just hang around until it gets received? or does it just fizzle out into nothing? Could my voice transmission be received at a time later than I transmitted it?

Ice falling from towers and guy wires is no joke. There's a tower in my area with a road that weaves in through the wire locations, meaning the road passes under the guy wires. They were so afraid of what falling ice might do to cars and people, they built a huge concrete roof over that part of the road. It's like a bridge except you drive under it, not over it.

Some people on the mainland South Coast, reported interference on TV channels from our "Big tower" when I looked at their locations, and looked at line of site from them to the Rowridge site, I noticed that our BAE System in Northwood (IOW) was smack in between them, BAE manufacture Defence Radars and their is a few Radomes on site, mysteriously painted in the MOD grey, is it possible those signals from the Radomes could cause interference in the TV signals..?

I'd like to know more about the lines feeding the antennas. Some of those are huge! How much power can they transmit, and why are some larger than others? Is that just for power handling?

Those cross polarized or circular polarized antennas are interesting in design… it would be interesting to see the actual construction of those. Curious to how the elements are connected physically and what is in the white cover. Any idea why they are tilted back at a 45 degree angle? I’m used to seeing that on ground radials or inverted Vs for HF but don’t understand the purpose on VHF or UHF elements.

Not long winded and heavy. More would be great. I love masts and towers!

They are simply transducers between electricity and electromagnetic waves.

Looks like my back yard !

[@davidsradioroom9678]

I really enjoyed this video. Yes, I would like to see more. Do people around the antenna receive all three BBC local stations?

[@RingwayManchester]

They will yes. To be honest I live 10 miles from it and receive all 3

[@glennso47]
