Since early July, my Freeview reception has been poor (Mendip Transmitter) with Pixelation and after retuning, loss of Channels( Sky News / BBC1 / 2 etc). This problems happens regularly during the summer when the trees are in leaf. I fitted a new external aerial last year but still the problems persist. My house has three TVs and all suffer the problem. I also has an 8 Way Aerial Splitter installed (SLX8).

Success! I have sorted out my TV problems FINALLY. It was merely a failed line amplifier which wasn't putting out enough signal (so it was indeed a mains issue). Aerial reception was fine. Thanks go out to Kevin from Wiltshire Aerials.
With a fair few loss of signal/pixellisation problems on the Mendip transmitter reported on here, could some sort of spike have messed people's signal/splitter/amp/picture up?
jb38 especially, thank you for your help with this. I must say I am thankful that I've found this website.

Ben Ward: Many thanks for your update on the situation and pleased to hear that you are fully operational again.
With regards to the powered splitter having failed, this as you will most likely have sussed out was the reason for my request (13th July @ 2.21pm) for you to try switching off the mains supply to the splitter, as if nothing changed by you having taken that action then it was positive proof that the unit was faulty, as of course it transpired that it was, but though I do fully understand your reasons for not being able to carry out the request by fact of its power source actually being in the loft thereby not being easily accessible.
And on the subject of the booster / splitter, if indeed its actual power supply had failed then nothing could really have caused that to happen excepting the possibility of its power transformer having tripped out (thermal fuse) through running continually in a slightly overheated state.
On the other hand though if it wasn't the more usual fault of the power supply having failed and the input to the device was connected to your outdoor aerial, then its likely that its transistorised input amplifier had failed through the aerial having picked up an excessively high level of static rain during some thundery conditions that may have occurred at some time, as boosters / splitters can suffer from this in exactly the same way as do some mast head amplifiers when connected to roof aerials.
Of course this latter comment re: input amp failing is never applicable at any time to loft mounted aerials.

Hi
I have a major problem with the BBC broadcast channel. Channel 48, 52, 54, 56 all reporting strength and quality 10 except Chan 61 carrying BBC transmissions. This has been constantly measuring poor to very poor on all receivers, PVR's dropping serial link on most programmes. Seem to have near perfect line of sight to Mendips. Post code BS22 9EF (Weston-super-Mare).

As there seems to be spate of aerial distribution amplifiers failing, I would suggest that, if
possible, a passive splitter is tried first. If there is sufficient signal strength, there will my no problems, and nothing to fail. My own setup is configured as follows: aerial to splitter, one side
of which feeds a Panasonic TV, the other side feeding a Panasonic DVD recorder/PVR, the RF output of which feeds a Humax PVR. The signal strength /signal quality bar graph on the
TV and Panasonic PVR shows 100% for both values; the figures on the Humax PVR
shows 79-81% signal strength and 100% for quality.

Jeff Glynn: Yes, passive types might be OK in areas where as you have said, a sufficiently high signal strength exists to be able to use them successfully, but unfortunately that doesn't apply to most areas that suffers from reception problems, plus!! you are using a combination of equipment fitted with top class tuners, as Panasonic and Humax tuners are about the best around, as the types fitted in most other brands are simply not up to their standard in sensitivity nor stability.
Humax of course being about the most accurate for its signal strength readings, whereas Panasonic is inclined to err slightly on the exaggerated side of reality.
