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?

Why do I lose signal from the Mendip Transmitter every night from around 6.45pm to 7.30pm on all channels. I live in Trowbridge, Wiltshire

As you can see, I live in Trowbridge but we do not suffer from any loss of signals at any time during the day or evening. Not knowing your exact location in the town, a post code would have helped, it is impossible to know what structures or businesses are nearby. Another factor that is common in this type of problem is electrical interference, possibly caused by some equip[ment that turns on at about that time. So would you check the cabling to the TV and any timer controlled equipment anywhere in the house. It is also possible that some external souyrce is the cause.

Well I also had low quality on the other muxes and bit errors. Whether it was total coincidence that when I went to "manipulate the coax" outside the signal varied (and disappeared) and then I was about to disconnect a connector inside to contemplate testing continuity to the aerial, the signal re-appeared and everything seemed to go back to normal. Checked the connection and all seems well now, so only time will tell if I get a re-occurence or a transmitter fault report eventually appears.

Hi, are there any issues at the mo with the Mendip transmitter? Using two tvs in the house both using different sources. One aerial in loft and one communal. Communal system has issues with freeview hd, roof aerial with standard freeview channels so I assume our equipment is working ok.Postcode is BA4 5UA. I see that the Bruton relay is having issues but assumed we were working off the Wells transmitter itself.Any clues or advice would be gratefully received.ThanksJoe

Hi there, there've been no reported problems for the Mendip transmitter. My issue seems to have been a faulty connection!
If your aerials are horizontal and pointing NW then you are definitely using the Mendip Transmitter. There would be no reason to use a Relay Transmitter as you have an extremely clear line of sight to Mendip and should have a virtually perfect signal being only 7 km away.
If you are having problems with the communal aerial, I would report it to presumably your building custodian/landlord.

I live in Trowbridge and one of our TVs cannot get a good signal on any channels...the other TVs in the house work fine...even changed cable and tried another TV with the same aerial cable in the same room and that works fine...what could have changed...I have tried re-tuning and manual tuning with the correct UHF numbers but stil pixellating on all channels with poor signal

Sandra Hares: If the TV that you report as not getting a good signal on any channels is found to be the same when tested on any of the outlet sockets used by other TV's? then the TV is defective.
One possible reason for the problem could be that the "inside" of the TV's aerial socket ("o" shaped section) has widened to the extent that it isn't gripping the aerial plugs middle pin, meaning that there is no electrical contact between both.
If on a visual inspection the inside section of the TV's aerial socket does appear to have widened, slightly crimp it together, or just crimp it slightly no matter what it looks like!

Steve Poile: Although in the interests of accuracy a post code is really required, however, if you are referring to Wellington - Somerset? (TA21) the two transmitters covering the area are Mendip @ 32miles / 57 degrees and Stockland Hill @ 13 miles / 153 degrees, the degrees in both cases only being approximate, hence why a post code is required.
