Ordered by the date of change, the list below shows all the UK’s main Freeview transmitters, plus about 300 Freeview Light ones. For each one is a list of the channel frequency numbers that have or will be changing.

The columns show the various multiplexes, for example PSB1.
The numbers in the table are the broadcast channel number, for example 42
OFF service being removed
tbc means I don’t have the final new allocations.
For simplicity, where a transmitter changes more than once, only the last date changed is shown here.
48 possible need for a filter when 5G services start.

Can't see any damage anywhere.
Tried removing the and monitoring BBC1 HD
strength dropped from 10 to 9
4 drop-outs in 5 minutes.

Replaced booster. Signal strength returned to 10. 5 drop-outs in 5 minutes, but each one about 1-2 seconds shorter than without the booster.

I assume that was direct to the TV and not via the HD HDD recorder.
Is the one with several outputs? If so try another , or do you have a splitter at all & if so where is it inserted?
Can you identify the type of , without disturbing it, has it got a coloured plastic bung in the end opposite the connections and reflector? Does it have x-shaped rods or straight ones? It might be a log periodic - google for a if you aren't sure.
At your location it should be pointing at a bearing of 230, that's a fraction W of SW. Are there any other objects especially metal or water tanks near the aerial?

Yes, straight to the TV
I did have a splitter in the , but I only use one socket, so I replaced it with the i had been using downstairs.
I have taken the best I could of my .
https://1drv.ms/u/s!AjISj…fgpM
Don't see any plastic bung. I see 8 sets of straight rods, though one set is bent downwards for some reason.
It's very difficult to get anywhere near it with a compass, so I can't confirm that it's pointing exactly to 230 deg, but I can confirm that all the other UHF are perfectly fine.
I don't have a water tank, but there is an aluminium flue about 3ft away

Oh dear, a cheap contract that's been damaged a bit, and it's not even one that has a decent !
With the way it's mounted and the direction it's pointing it doesn't look as though there's much room (if any) in front of the aerial?
Where is the flue in relation to the aerial? Is it right behind or to one side - again a may.

I guess you don't want to get an aerial installer in unless you absolutely have to? Is there any boarding on top of the beams supporting the ceiling? If need be, could you put some (temporarily perhaps) so you could try and get to the back of the aerial?
The coloured bung (might be black) is in that far end of the square section on which the rods are mounted.

The "rods" should all be horizontal (not bent in any direction) and should be square on to one another and to the "dipole" part that is just in front of the grid reflector.

Do you feel/are you confident enough to get to the aerial and make some adjustments etc. Are you likely to have a spanner of the right size that undo/do up the nuts on the clamp at the back of the aerial where it's mounted on that pole?

Chris.SE:

Thank you so much for your time, help, and advice.
I have taken more pictures:

https://1drv.ms/u/s!AjISj…7jjX

They show the bung at the end, before & after pictures of my attempt to straighten the rods, and the position of the flue, which I would say is abut 2 ft to the right of the reflector.

If necessary, I believe I would be able to buy a new, bigger, , move the attaching pole to the other side of the beams to give it more room, and to rewire it.
I would not, however, be able to do much of a job of pointing it in the right direction with any accuracy.

What is the significance of the bung? Were you just making sure it was there?

Cheers,
Gilbert

Hi Gilbert, the significance of the bung is its colour, it "should" indicate the band. That one looks Black suggesting it's a , if it's more grey it could be a group K, either of which are okish in that they cover the broadcast from , the primary issue is at channel 21/22.

Now having said that, aerial position is also a major factor and it can sometimes be a bit of a black art. One thing you don't want is that flue or that to the left, in front of the aerial. The flue to the side could be having an effect, if it were behind it might have less effect but again I'll repeat things can be a black art as beams can sometimes have unexpected effects and you don't want that wall that's in front, in the "line of sight".

As far as the direction is concerned you don't really need to get the compass close to the aerial. Anywhere eg. from where you took the of the flue would probably do to see if it's roughly in the right direction - 230 degrees is 5 deg. W of SW and in any case because of "things in the ", exactly 230 degree may not be optimum, nor come to that maybe the current height!

The question is, so far, has straightening the rods on the aerial had any effect? If so what effect? Make a note of the current position of the aerial, maybe by a mark on the beam at the front of the aerial in it's current position.

If you are up for a bit of experimenting, we could get some idea of how sensitive the position is. Depending on the effect so far, I would try lowering the aerial on the pole, say by 6", keeping the direction the same (this will allow you to change the direction a bit - later - as at present it's too close to the beams to give any freedom of movement). See what effect this has on the strength of each - I would start writing things down so you can compare before and after effects.

Having got an idea of where 230 deg. is, if it's currently pointing pretty much that way and lowering it hasn't had disastrous effects (ie. drops in across several multiplexes, a slight drop in signal may not be of too much concern) then I'd try changing the direction a bit. First, if it's not pretty much on 230.deg, I'd turn it towards that way and check the effect. You can also try turning it a bit further in the same direction. Again, note down exactly what the effects are on each multiplex. Then try turning the aerial the other way, a few degrees at a time and note down the effects. Eventually you may be able to draw some conclusions about an optimum position.

Depending on the results, whether or not changing the aerial might be more beneficial might remain to be seen - you might be able to get some satisfactory results just from repositioning.

Chris.SE:

Thanks again.
I'll do some experimenting.
The major thing that seems to have had an effect so far is the removal of the old splitter from the equation. That has reduced the number of drop-outs considerably, but not completely, which means I still can't watch HD.
If the experimenting doesn't fix it, I'm thinking of buying a new .
Here are the aerial and I was looking at:

https://www.screwfix.com/…0515

Webro WF100 10 m Low Loss Digital Satellite Coax Cable: Amazon.co.uk: Electronics

If I can't fix it for free with a bit of experimentation, 25 doesn't seem too much to me.

The existing is 850mm. The new one is 1240mm, but I can re-site it to have more room, and away from the flue. Also, it can be centrally mounted.
I tried adjusting the position of the current aerial, and may have got it marginally better.
HD now goes for up to 15 minutes before dropping out.
Since it's only 25, I minded to just get the new aerial and .
That one will surely do a better job, don't you think?

If you are prepared to buy from Amazon then I would suggest this one -
Digital TV Aerial, SLx 27884D4 4G Filtered Loft & Outdoor 48 Element Aerial for Digital TV High Gain Wideband Freeview HD: Amazon.co.uk: TV

It's the same part number (27884) but it's a 4G filtered version (SLx, Labgear, Philex, all the same group!) & only 1.65p more than Screwfix. There is a version that comes complete with mounting kit and 10m , but I suspect the cable supplied with that might not be as good a as the cable you have already listed from Amazon.
