You have now posted in 3 different places and don't appear to have read (and hence responded) to the reply I gave you here Get to see your Freeview predictions map | free and easy
Please respond with the information requested there and we may be able to offer advice.
There are no current or recent faults listed for any of the transmitters that you might receive, so this all suggests the problem is with your own aerial installation.

Karl:
Some very practical advice there Karl covering issues that some of us have come across. If you are in a strong signal area, yes those "mini" logs seem ok but I haven't installed one personally. I'm not sure the length (from the CPC site?) is correct, Labgear quote it as 445mm. Blake also do a 22-element (mini) log either Group K or Group T both 450mm long and slightly better gain. If anyone needs one now and can get COM7 then Group T is needed, otherwise go for the Group K. Blake seem to have addressed the weather-proofing of the F-connector issue, but there's always belt and braces with use of a bit of silicon sealant or self-amalgamating tape.

Forgot to add as a general buying guide, watch what and where you buy, don't go just by description, look for spec. - I've seen some aerials described as High Gain that are definitely NOT "high" gain, watch postage as well as unit costs.

Could it be one like this? https://cpc.farnell.com/s…3503
If not, is it rods or Xs on the boom?

StevensOnln1:
TBN is on the BBCB HD/PSB3 multiplex as StevensOnln1 has said, which is on UHF C46 at Kings Weston.
However there are some errors at the top of the page, some of which are common to all transmitter pages here, as it shows Shopping Quarter LCN72 still on PSB3 when it moved to ArqB some time ago.
See Channel listings for Industry Professionals | Freeview for a up-to-date list of which channels are carried on which multiplex. (except it still shows 679 & 680 which have now closed but seem to be still licenced).
The list doesn't correctly show the Bristol Local mux which is on UHF C31 at Kings Weston.
There's a query on the power for the 6 main muxes. The OFCOM 700MHz Clearance document shows the power as 200W whereas DUK are showing it at 250W. As already stated there is no COM7 at Kings Weston.

Are the rods (or squashed Xs) on your aerial horizontal or vertical? Rowridge has both polarisations for the 6 main multiplexes, but only horizontal for COM7 and the Local Multiplex.
If the rods are horizontal, you should have no problem receiving the Local multiplex - UHF C37.
I can't find any faults currently or recently listed and there is no Planned Engineering listed.
I would check that your aerial seems intact and pointing in the correct direction and that your downlead looks undamaged (especially if it is old).
Also check all your coax plugs, connections, flyleads etc, unplug connectors check for corrosion or other problems and reconnect them. Flyleads are a common problem, try swapping/changing them.
See what signal strengths and quality you are getting for the multiplexes (groups of channels) shown in your TV's tuning section, that information may indicate issues with your aerial or downlead or possibly any distribution amp/splitter you may have.
Problematic connections, water ingress etc. can seem to affect reception of just [b]an individual[/b] or several multiplexes.
Have you changed anything in your setup at all?
Make sure you don't have any HDMI leads near unscreened/poorly screened flyleads/aerial leads especially if those aren't double screened coax as HDMI has been known to cause interference.

John Watson:
LCN51 Great! Movies Xmas (along with some other Great! channels) is carried on Local Multiplexes. They were moved there by the previous owner of the channels (Sony) back in July 2019.
See Channel listings for Industry Professionals | Freeview for which channels are carried on which multiplexes.
Local multiplexes are transmitted on a small number of main transmitters and are beamed towards the centres of population they were setup to serve.
In the case of Belmont, it's beamed towards Grimsby and Hull. Bridlington just happens to be on the very periphery of predicted reception with variable reception.

I can't find and current or recent faults listed for Wenvoe and there's no current Planned Engineering listed.
If there was a Wenvoe transmitter fault there would be many posts about it, so this suggests a problem with your own installation.
Have you checked the connections behind your TV? Have you changed anything in your setup at all?

aytch:
Hi aytch. Same to you, hope you've had a good and healthy Xmas and the same for 2022.
Now during the week following the 16th, there was a lot of tropospheric ducting around with the high pressure weather conditions at the time. A lot of people had problems with reception across many places in the UK.
Those conditions didn't clear until Thursday the 23rd.
Has your reception been more stable since then?
Weather conditions such as rain can have an effect with loft aerial installations, but providing you have sufficient signal it can go un-noticed. Trees on the line of sight can be an issue when close, but I would have thought that 2 mile away would not have a big effect
What would be useful as I don't think you've ever posted the information, would be to look in your TV's Tuning section - it may be a section called Signal Strength/Information ... or in the Tuning area.
If you can post the Signal Strength and Quality (or Bit Error Rate - BER) for each of those multiplex UHF channels. This will give a much better idea of how good the reception is.
As you know, your aerial configuration is far from ideal. Is it practical to run a separate downlead from the TV aerial?

StevensOnln1:
Hi, thanks for your post. I had come across cellmapper but not found it particularly intuitive to use. It also seems to suffer problems with cell locations on maps with some cells I'd looked at - similar to AM/FM mast locations on this site!
Any ideas why that might be?
