I believe it's also beamed in an ESE direction towards Spalding and maybe as far south as Peterborough, so if you live in an area bounded by them and the transmitter you might be able to receive the Local multiplex. Try a Manual tune on UHF C41 (auto-tune may miss it if the signal is weak but just receivable).
Local multiplexes are only provide at a limited number of main transmitters and signals beamed towards specific largish centres of population due to the limited number of channels available and costs involved in providing commercial services.

The Waltham transmitter had been listed for Planned Engineering a few weeks ago for several weeks. It's possible that some work still needed to be done although the transmitter isn't currently listed. I can't find any faults currently listed either (there could still have been one!).
Do NOT retune, this will most likely just clear your correct tuning and you'll have to repeat the process when signals are normal.
Check with neighbours if they have the same issue, if not, do check your aerial looks intact and is still pointing the correct way, that your downlead looks intact and is not flapping in the wind, and check your coax plug connections etc behind the TV.

This last week, I have been having problems with a few of my Freeview tv channels. There is a 5G mast (DE22 1FL) about 30 metres away from my property (DE1 3HJ). Are the updates to Waltham in connection with this?
Thank you,
John

Which Channels have your problems been with? Has it been continuous or just now and again and roughly how frequently and what sort of duration? What sort of problem - pixellation or no signal?
Arqiva never give any details about the Planned Engineering work - usually routine maintenance - it's very unlikely to be any update - at least not affecting any normal transmission and it's highly improbable to have any connection to a 5G (if it is) mast near you. The mast may not even be operating in the 700MHz band anyway - 5G has several allocated bands.

Hi Chris,
I notice the problems mainly with channel 39 when I record overnight/early morning shows. I get problems all during the day, though one morning the pictures were fine, then after 9:00am, I had the problems back...
I have problems with channels 11, 39, 56 + 69. Sometimes the pictures are fine, then a hour or so later, I have the bad signal sign, pixelations, picture break up or even no pictures!
I have had the problems before, and a repairman came out, then had to get a fine-tuner to adjust the signal reception and everything was fine for a good while. Then a couple of weeks ago, I noticed the problems had returned. It seems the repairman for the communal aerial doesn't have a fine-tuner... Would it just be simpler to buy a signal filter/booster?
Thanks,
John

First, a quick answer to that last question - No!
All the channels (programmes) you've mentioned are carried on the ArqA/COM5 multiplex, which is on UHF channel C37 at Waltham. Were the previous problems with the same group of channels?
(See Channel listings for Industry Professionals | Freeview for which channels are carried on which multiplex).
Now there's a couple of possibilities here.
The first, you've mentioned you are on a communal system. I'm assuming that the mention of "fine-tuner" to adjust the signal is a reference to that fact that a lot of communal systems (especially larger ones - roughly how many are on your system?) have what's called a channelised distribution system.
The aerial signal is fed to a number of filters and pre-amps specific to each UHF channel in use at a given transmitter. This is so that the signal strength of each UHF channel can be adjusted separately so that they are all as equal as possible and within the correct range when distributed to all the outlets in each of the premises it serves.
They obviously can go faulty from time to time.
Have a look in your set's tuning section for signal strength and quality (or error) figures. Make a note of the figures for UHF 37 when you are not seeing a problem and when you are, and compare to the other UHF channels for the other multiplexes and make a note of them. Whatever the signal strength figures (not overly important as long as they aren't too low (or excessive) as long as the quality figures are 100% (or error figures zero or very low).
I've mentioned "excessive" signal strength - this is why the answer to your question was "No". Just because one channel was/maybe low (when the others are at the correct levels), if you amplify all of them you can overload the front end of your receiver which can produce pixellated pictures, sound break-up etc. Filtering individual channels in a "domestic" set-up it not practical and would be very expensive if you were to try and "emulate" a professional distribution system.
The second possibility is a fault with that multiplex at the transmitter and the reason for the Planned Engineering. Only time will tell. If you post those figures it may give us a clue.

Good morning Chris,
Yesterday the pictures and signal strength were excellent. But this morning, the pictures on the problem channels are all breaking up again! I was hoping that my difficulties were due to Waltham upgrades, but today, I do not what to do...
Thanks,
John
