Which companies have run the Channel 3 services in the Mendip transmitter area
Iain Davies: I doubt the local mux has been moved to the main aerial as it would cause massive interference with the Cardiff local mux which is also broadcast on C51 from Wenvoe, which has large areas of overlap with the main muxes from Mendip.

There has not been any engineering work reported at Mendip so there has been no known change to the aerial usage.
100% signal strength is too much. What is it like on the other multiplexes? You ideally need between 60% and 85% for good reliable reception, any more and there is a high risk of break-up and the strength should be reduced by using an attenuator or turning down the gain of any amplifier fitted in the aerial cable.

Something has happened, as from zero % age to 100%. This shows on the signal meters on my Panasonic blu-ray recorder and Humax HD hard drive box. I used to live to the north of Mendip but now living south as I said until last Friday the signal was nil!

From what you report it very much sounds as if you have problems with your aerial or the cables connecting it to the TV set. Please carefully check all the connections and ensure thatbthere is no visible damage to the cables. then unplug all aerial onnections and plug them back in (that is to ensure there is no oxidation of the contacts, which often causes the problems you report. Then check the signal strengths of all the multiplexes broadcast from Mendip, they should be no less that 50% for the SD services and no less than 60% for the HD services. None of them should be more that 85%, if they are then that will also cause the problems you report.
Finally, please enter you full post code so thet we contributors can check what the signal transmission and reception conditions are at your exact location.

MikeP nope nothing wrong with my aerial system, brand new just installed by me. I have installed 1000s of aerial systems with no problems, from the North of Scotland where there was hardley any signal to places you could get perfect reception on a two inch nail!

Ian Davies: Perhaps if you were clearer you might get more constructive comment. On which aerial did you notice this "change" in signal? You've just mentioned an outdoor Mendip aerial the implication of which is you have an indoor one as well, and there's also this Stockland Hill aerial. Are all the aerials "grouped" or are they wideband? Are the aerials coupled at any point before being fed to the TV(s)?
In any event, there has been no change to the local Bristol Mux. I'm 40 miles N of Mendip and getting it on 74% signal 100% quality as I usually do.
I do get occasional variations in strength when propagation changes. I suggest that it was such an event that was enabling you to get the mux of the back of your Stockland Hill aerial, recent weather pattern changes would usually cause some change in propagation.
