The symbol shows the location of the Mendip (Somerset, England) transmitter which serves 720,000 homes. The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.
Are there any planned engineering works or unexpected transmitter faults on the Mendip (Somerset, England) mast?

Can anyone advise if the Burrington transmitter send signals higher than its mast as we can see the mast from the top of Burrington Combe and initially got 22 chaneks from downstairs room but in lft then on roof only get Wales and weak signals ? Took it back to lower level and no signal. Pointed it at Burrinton mast from upstairs window, direct line between trees but our elevation up 150 feet or so. Still get only Wales. Should I get Burrinton signal or do I have wrong arial? I had 64 element hgh gain from B&Q.

Lance Forbat Forbat: Yes, it will just in roughly the same way as it does downwards, I noticed though that the predictions of your expected signal level from it aren't 100% even although its only listed as being 1 mile from you, plus as its shown as being located at approx 5 degrees from you I would have expected maximum strength considering the transmitter radiation pattern is basically heavily biased towards the South / South East, with a rapid cut off from the South sweeping towards West.
However all six multiplexes from Wenvoe are shown as good, particularly BBC1 etc, as so for maximum channels you would be best concentrating on reception efforts from Wenvoe as Burrington as you will probably realise is a PSB only station anyway. (limited channels)
I think you are a bit over the top in the aerial you are using, and in the circumstances you are in a Log 40 would have been much better, as these larger aerials only really come into their own in line of sight (or near) situations where exceptional distances are involved, and indeed can perform very inferior to smaller aerials when not used in the circumstances mentioned.
This is the type of aerial referred to.

Lance Forbat: Just to add, Wenvoe is shown as being located at 25 miles from you at a bearing of 292 degrees and the mux channels used by Wenvoe are:- 41 - 44 - 47(HD) - 42 - 45 - 49. Its always best though to scrub anything stored before trying another station, and with Wenvoe using lower channel numbers it should (hopefully) populate the EPG before Burrington as it spans Ch53 - 60.
Nothing can be guaranteed with RF reception, and the fact of you stating that the signal vanished with the aerial being higher up suggests some signal path peculiarities are occurring in your area, especially where a transmitter at only 1 mile away is involved, as radiation patterns do not generally show any upwards cut off measures that "may" have been taken.

Could someone please tell me why I keep being unable to watch any of the BBC channels. They frequently have either no signal or are so pixellated that they are unwatchable. Seeing as the BBC is the one I pay the licence fee for this is extremely annoying. I live in BA4 area.

Thought I might post this as it may be of help...
BA4 5XD, steep wooded valley in Bowlish, Shepton Mallet. I have had 70%/low/disappearing signals varying across the spectrum from Mendip, even though the transmitter is only a couple of miles away. This weekend the neighbour's 3 gigantic Leyland Cypress (Lelandii) trees were removed from the general line of sight and now I'm getting 88-95% signal on all free-view channels. Although the transmitter tower is still not visible the signal must be bouncing around better from the sides of the valley.

I wish that could be of help to me but there is nothing I can do about trees.
Have done a retune and now have no BBC channels whatsoever.

Tracy Gill: Check if you have another version of the BBC channels anywhere else in the channel list (usually from 800 upwards). If they do appear, the problem is that your box is tuning in the weaker signal from Stockland Hill rather than the strong one from Mendip.
Unfortunately a lot of equipment designed before switchover started simply stores the first channels it finds. That was fine when power was low and most people would only expect to have strong enough signals from one transmitter. After switchover, many - perhaps most - people will have strong enough signals from more than one transmitter, at least strong enough to decode and store the channel list even if not strong enough to actually use.
See Digital Region Overlap for thoughts on resolving this. Newer equipment should ask which region you want, if more than one is received, and use the best available transmitter for the selected region(s).

Tracy Gill: Following on from Mike Dimmick's suggestion that it could be that your receiver has tuned to Stockland Hill and put Mendip in the 800s, I looked at the channel (frequency) allocations for these transmitters.
If this is your problem, then you should be able to correct it by running the automatic tuning scan with the aerial unplugged up until about 45%.
Stockland Hill uses channels between 22 and 29 and Mendip uses 48 to 61.
You will need to retune on 28th March due to a channel change for Arqiva A which carries Pick TV and others. This will not affect the procedure I outlined above as it is still within that range of channels.
