Although living well outside the service area for Mendip BBCA and D3&4 have always provided good reception here in North Herefordshire.
Since the change of BBCA channel to C49 I can no longer receive this multiplex, constant breakup and high error rate.
The D3&4 Mux on C54 also seems to have dropped off a bit as I am now starting to see higher error rates on this channel also.
I suspect the ERP has dropped off since the change.
I only had a 2dB margin on my analyser on BBCA and D3&4 so a little bit of margin above the cliff edge. I would say the results I am seeing point to a 2dB drop in power received at this location.

I live in Penarth in a three story victorian house not far from the sea front with a high gain aerial in the loft pointing at the Mendip Transmitter. The aerial was installed in the days of the analogue service. Since the change over of channels which took place in late March 2013, I now experience poor signal strength on channels C49, C48 and C52 with good signal strength on channels C54 and C56. Will need to change this high gain aerial to receive all the channels transmitted from the Mendip transmitter?

Roger Alban: First off try rotating the aerial a bit. Or if that doesn't work, maybe try the aerial in different positions in the loft-space to see if you can find a spot where all channels are good.

@Chloe, If all else fails I would be prepared to offer assistance as I live in Taunton (TA3) and reception here is excellent. None of my neighbours have a problem with BBC, nor any friends who live in town. I have odd bits of test & diagnostic equipment that could be put to resolving the matter which seems to be very localised.

Hi, I am wondering why I am unable to pick up Film4? I have a Freeview Digital TV and live in central Stroud. Has it got something to do with the power of my ariel or does the Stroud area have limited frequencies? I have tried retuning.

Many thanks for anyone's help?!

Jonny: If you are receiving from the Stroud relay, or "filler-in" transmitter, then you will not have the Commercial (COM) channels; it only carries Public Service (PSB) channels.

For a list of which services are carried on which multiplex (i.e. which are PSB and which are COM), see:

DTG :: DTT Services by Multiplex

The COM channels only broadcast from the largest transmitters as their prmiary objective is profit and they have no "Public Service" obligation. See here:

Londonderry (Northern Ireland) digital TV transmitter | ukfree.tv - 10 years of independent, free digital TV advice

If you are receiving from Stroud then you may be able to receive the full service from another transmitter such as Mendip or Wenvoe. The latter carries Welsh regional programming and you may be able to use a separate receiver for it (or use Wenvoe as your main transmitter and Stroud via a separate set-top box for regional programming).

Jonny: I would suggest that you're not likely to be able to receive from Mendip and that you're only option in the centre of Stroud might be to receive all channels from Wenvoe and regional PSB channels from Stroud. Unfortunately due to the channels (frequencies) used by these two transmitters being interleaved, you won't be able to have the two feeds (from each aerial) combined so as to feed it into one receiver.

Jonny: probably best to check your postcode on this website to see what your forecast coverage is likely to be.

Depending on where in Stroud you are, I would imagine the hills surrounding the Five Valleys may get in the way of the main signal from Mendip. In that case, you may be getting your signal from a local public service relay. For example, Stroud has its own relay (https://ukfree.tv/shutdowndetail.php?tx=SO836077), which you may be getting if your main BBC1 channel comes in on UHF 40 (on Mendip it comes in on UHF 49).

If it's only relaying public service ("Freeview Lite"), then I think you'll only get PSB1, PSB2 and PSB3. Since Film 4 is on COM6, a commercial set of channels, you may not be able to get it at all.

Are you also missing channels such as ITV4 and Yesterday? Can you get Dave or ITV3? These are all on commercial UHF channels which the Stroud transmitter is not relaying.
