Freeview reception at PGSTART 100
For reliable and stable Freeview reception, you need an unobstructed path between the TV aerial on your roof and the digital TV transmitter. The map below shows the transmitters predicted to provide a signal at this location.
You can click on any transmitter symbol to show the coverage area as a green overlay on the map. Double click on a transmitter symbol to go to the transmitter information page.
You can also view the ten closest potential '4G-at-800' mobile phone masts within 1.5km of the selected location - these masts may be used for 4G-at-800 mobile broadband services from 2013-2015.
These icons show the potential locations for 5G-at-700MHz services that may interfere with Freeview reception. For actual mobile device reception prediction (at 800-960MHz and 1710-2170MHz) see these phone operator's mapping sites: Three O2 EE VM

I'm based in the Wirral area and I think I may have some 4G interference. Can you confirm this?

Laura Sharpes: Unless you are managing to pick up 4G signal from South-east London or Brighton (which is impossible) then you do not have 4G interference. Though I'm curious as to how you would be able to tell what 4G interference looks like!

My freeview tv is tuned in via Sutton Coldfield. Would Waltham be better?

Ash: There are a number of factors to be aware of and consider.
The COM channels from Waltham are at half power to the PSBs, the former being 25kW and the latter being 50kW.
All channels from Sutton Coldfield are 200kW.
Looking at Streetview and satellite images there are quite a few trees in your area that may perhaps rule out, or otherwise make difficult, reception from one or both transmitters.
Sutton Coldfield carries West Midlands programming and Waltham carries East Midlands programming.
You don't have clear line-of-sight to either transmitter.
The Derby transmitter, situated in Littleover at the Fire Service HQ, relays Waltham's PSB channels. It is on practically the same bearing as Sutton Coldfield and may be available to you. Its purpose is to provide East Midlands programming to those who otherwise receive from Sutton Coldfield. It does not carry the COM channels so you would have to rely on Sutton Coldfield for them.
For a list of PSB and COM services, see:
DTG :: DTT Services by Multiplex
In order to receive from Derby you may have to resort to manual tuning.

The aerial is on my chimney, approximately 13 metres above ground. It receives Freeview Light from Rhondda at Llwynypia. For the last 16+ years it has entered a powered booster/splitter box in the loft. A loft-installed hi-fi aerial also enters the box, from which three coax cables serves three tvs and separate cables to three hi-fis. This system has worked without problem at all times and since Digital changeover, until recently. All BBC channels suffer from pixelation intermittently. On my Samsung tv the maximum signal strength is shown as 50 with small bit error readings, and it just about copes but when the problems arise the SS reduces to mid 30s or less and the Bit error shows major fluctuations and sometimes no signal. The other tvs are Panasonic and they cope better but still pixelate on occasions. The other channels show 70 with no BE activity, and very good pictures. My immediate neighbours with the same line of sight to the transmitter but from an aerial at half the height have no problems. It seems to me that the potential problems point to the aerial and or splitter/booster box. I am 75 and can no longer access my loft to check. I am sorry to bother you but would appreciate any views and advice. Thank you.

Graham Cole: I would suggest that the signal amplifier is pushing the level of the signal up too high:
Freeview signals: too much of a good thing is bad for you | Digital switchover | ukfree.tv - 10 years of independent, free digital TV advice
If this is the issue then it may be that it is just managing to cope with it at 50%. At times it goes higher.
Think of turning the sound up on a piece of audio equipment where eventually the sound will distort and you loose quality. That's effectively what is happening if your TV signal is too high.

Thank you Dave for your very swift response, which I have only just read. Having looked at the link, how can I check if the problem is as you suggest, and, if so, will I need attenuators on each set, or cables in the loft , or one on the feed into the booster/splitter box. On reflection, I cannot remember whether the loft box is a booster/splitter or merely a splitter. If it is the first would it be better with a splitter only? Thank you for your patience with a 'silver surfer'.
