Barrie:

As already mentioned there is Planned Engineering listed for Mendip at present. If your set auto-retuned when signal was interrupted (if it has that function turn it off, it's more trouble than it's worth) or you retuned, then as StevensOnln1 has already said it can clear the correct tuning!

At time of posting Mendip is transmitting at normal power, try a manual tune on UHF channel C32 (the BBCA/PSB1 multiplex) to see if it restores the channels. If you have an HD/T2 tuner and the HD channels are also missing, try a manual tune on UHF C35.

If you still have no luck, as already advised, check connections and check your aerial is intact and still pointing in the correct direction. If you need more help, please provide a full postcode so we can examine predicted reception at your locale.

How old is your aerial?

The Sony Movies Classic channel is broadcast on the Local Multiplex which doesn't have the same coverage as the other main multiplexes carrying other main channels BUT it should still be receivable in most parts of Chipping Sodbury, see Channel listings for Industry Professionals | Freeview for which programme are carried on which multiplex.
As StevensOnln1 has already said we need a full postcode to look at predicted reception in your locale.
The Local multiplex is on UHF channel C30 from Mendip. You could try a manual tune as that may pickup the channel. Auto-tune sometimes misses weaker signals.

If your aerial is an old aerial group C/D then you may have occasional trouble with the main BBC SD channels (the BBCA/PSB1 multiplex is on UHF C32) and may not be able to get the Local multiplex on C30. These days you may need a Group T/Wideband aerial to get all the multiplexes satisfactorily (depending on location).
Do you have intermittent problems with other channels?

Loss of many channels, some HD and some non-HD since November 2020at BS30 6US.

Sometimes some work after retune but only for a few days. Loft aerial checked for direction and fitted with 18dB amplifier then fed to 4 output splitter.

Lounge: LG HD tv, Youview + HD box for Prime via wi-fi.
Bedroom: Sony tv, Youview HD box not wi-fi.
Kitchen: Samsung HD tv.

John Bell:

According to the Freeview checker you should be getting virtually perfect reception from Mendip in your locale.
Is the loss of channels the same on each set? Some more detail might help, is it LCNs101-105, or 106/107 etc.?
Example channel LCNs may help to narrow down the issue.

How old is your aerial roughly? Likewise, how old is the amp (and splitter)?
Is the wiring to the amp & splitter plug-in connections? Check all your connections to make sure they're making a good connection.

If easily possible connect the aerial output direct to the feed for the Lounge TV and in the lounge, plug the aerial connection direct to the TV. then go into the TV Tuning section, look at Programmes and Settings, and then go to Signal strength. Post up the Signal and Quality figures for each multiplex.

I need to buy a new aerial after my builder removed the old one during the removal of our chimney. I am not sure what external aerial I need to buy to replace it. I live on hill in Weston super mare with a clear line of site to the Hutton transmitter but I would like to connect to the Mendip transmitter?

Paul hudson:

If you mean Hill Rd. in WSM then you stand a chance BUT that's a guess on my part, we do need a full postcode to look at the predicted reception. If you look at the coverage map above with Pro-mode enabled and zoom in, you can see the general difficulties in the WSM area, but do not take the map as 100% accurate, these things aren't always the case (nor are predictors) but they give a general idea.

Which way are you neighbours aerials pointing? Are the rods (or squashed Xs) horizontal or vertical? If they are horizontal and pointing roughly ESE (although depending on location Hutton maybe roughly the same direction but vertical rods) then you may get Mendip, but a full postcode will give a far better idea.

If you want all multiplexes from Mendip, you'd need a Group T/Wideband aerial BUT if predicted reception (especially of COM7) isn't good, you might be better with a Group A and forget COM7 (but again you might get that off the back of the aerial from Wenvoe. Whatever, do not be tempted to buy one of these "baco-foil" aerials from certain DIY outlets, the first pigeon or two to land on it will bend things all over the place!
Once we know what the predicted reception might be and what your neighbours are getting, we should be able to give some sensible choices.

I live in Stonehouse No7 GL10 3QP and have a new roof top wide band aerial pointing at the Mendip transmitter but have bad signal quality on all the HD channels.
Using my TV signal information I get;
Ch Sig Quality BER
32 94% 100% 0
33 92% 76% 0
34 92% 50% 0
35* 92% 40% 1268
36 92% 48% 0
37 0% 0% 2,000
48 100% 100% 0
55 96% 0% 2,000

I get a slightly better HD pictures if I tune into Wales, but cannot move C5HD & C5HD to 104 & 105;
Ch Sig Quality BER
47 93% 70% 0

Should I change the aerial to Group B to try and get some more gain in signal strength? Other thoughts?
