I have bad break up,freezing on the following Channels 11,12,17,29,32,36,46,48,and 82.
Plus I get picture freezing etc when I turn on lights or use power devices.
Why, and what can I do to improve the situation.
Any advice would be appreciated.

John: What is the signal strength and quality on C22 compared with say C24 or C25? Select the frequency as if doing a manual tune, but do not press store or save to take readings of the signal being received. If C22 is shown as having lower strength or quality than the other frequencies it could be that the aerial needs slight repositioning to get a clearer view of that particular signal. With regard to interference from switches etc it is advisable to have good quality double screened coax for the downlead and any fly leads to prevent interference pick-up by the cable. Having the aerial mounted for vertical polarisation might prove beneficial, depending on your location, as the COM muxes including C22 are transmitted at 200kW vertical and only 50kW horizontal from Rowridge. If replacing your aerial a log periodic, or a group A yagi fitted with a pcb balun should be chosen for reception from Rowridge. Avoid the wideband models on offer in DIY outlets as these do not perform particularly well on the lower UHF frequencies as used at Rowridge. A good installer should automatically fit the correct aerial type as suggested above.

JOHN-
To assist you can you please provide
Your location
The type of aerial you have ie red or black tipped
The location of your aerial
How many TVs connect to the aerial
Do you have an amplifier
thanks

I may have posed this question on here before but now I have more data.
I live in Weymouth & have installed a Group A high gain aerial with a mast head + 25 DB booster.
I obtained a compass bearing from my house to the Rowridge transmitter from the local Coastguard station of 86 degrees & lined it up exactly.
I can get good strength signals on multiplex channels 24, 25, 27,& 28, but on channel 22 which has 2 stations I require, Sky News & Dave the signal strength is pretty steady @ 64 but quality poor to nil.
The modulation alternates between 64QAM to QPSK, I have no idea what this means.
If anybody can give me an explanation why when all of the other channels are ok why should 22 be any different when they are all produced from the same transmitter.

Idris Martin: Although the channels referred to might well come from the same mast they are all being radiated from different heights on the mast (BBC at top) by a series of phased panels positioned around it at these different levels, and with this type of system no matter how carefully these panels are positioned the signals beamed out from the mast will never be anything even remotely resembling parallel lines, hence the main beam from some channels might suffer from one of the three main problems that can affect an RF signal, and being - reflection / diffraction / scattering, whereas another beam might not hence why the difference in levels.
The fact of you having previously reported that Ch22 can vary dependant on whether it be a sunny day or not somewhat indicates that Ch22's the signal path suffers from one of the aforementioned potential problems, and of course the further away a person might be from a transmitter (48 miles in your case) the greater the chance of being affected.

Well thanks jb38 for the info it seems I will just have to grin & bear it.

I live in Bryanston, Dorset (DT11 area/Blandford). Since the digital switchover a few weeks ago, we have been receiving digital TV via Mendip very successfully. Now we cannot tune in any channels successfully, using Rowridge, Winterborne Stickland or Mendip. We have moved the TV aerial every which way to no avail. The signal strength/quality is particularly poor in the mornings but is often very good in the evenings, which makes no sense at all. We can't understand what's happened.

I work around Southampton and for the most part all
I use now are Vision log 20 Group A(V), they are perfect and in most cases there is enough signal for 4,6, 8 or more TV's.
I seem to spend a lot of time at customers premises
stripping out all the old amps as they are saturating the
signal.
If I am over the West End side then I use group B's
I find it strange how you still see installers using great
big wide band wind catchers pointing them
horizontally at Rowridge. I suppose from a customers point of view
the more metalwork there is, the better the signal.

Alan Rowe: Quite so, and especially the latter comment you made, as although I am not an aerial installer as such I do sometimes get involved with aerials and find that many are initially sceptical about the results expected when their huge piece of metalwork similar to a garden railing is removed and replaced by something a fraction of the size, me of course also referring to log periodic's.
