The symbol shows the location of the Crystal Palace (Greater London, England) transmitter which serves 4,490,000 homes. 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 Crystal Palace (Greater London, England) mast?

Rob: Thank you very much for your advice jb38.. When i am better and got a bit of cash i will go a buy a log aerial from satas whos just down the road where i live. they have logs on enay for avery good price....so will keep you up to date when i get the chance to try it out.

Kevin what aerial do you is it new one or old one...If the aerial is old one... check the cables if possible replace them with double screened cable and make sure the aerial is correctly lined up..an small movement can mess up the the signal. so try move it a little at a time till the signal is 80%.. i find if its 100% it be too much gain....will cause problems.I do think for London it should be a Group A areial the reason for that its group A's have a really good gain and picks up Crystal palace... If the booster is very old... try replacing it... i had one of mine burnt it self out. Hope my tips helps.

Thanks Rob. I have an aerial that I bought from B&Q for about £20 8 or so years ago. It is wideband, rather than group A.
Last night, I moved the aerial completely and pointed it at the Hanington transmitter. This seems to have done the trick, although I haven't carried out enough testing or getting the positioning perfect to ensure it is as good as it can be. I did however notice the Freeview HD channels were fairly week. When you say aim for 80%, I assume you are referring to signal strength rather than quality. Presumably I do this via the variable gain on the splitter.
The booster is probably about 15 years old - it is one of the bean shaped One For All boosters in blackwith 4 outputs and variable gain. I only use one output, would I benefit from getting a single output booster?

You asked if your problems could be related to 4G work. As you're using Crystal Palace which transmits in the lower end of the UHF band it would be highly unlikely to be anything related to 4G. Channels 60 and above are now cleared of DTV signals to make room in the spectrum for the forthcoming 4G signals. At present CP transmits on 22, 23, 25, 26 and 30, with 29, 33 and 35 to come next year. So any 4G signals are well outside that range. Plus the only 4G signals in the 800 MHz+ range are test signals in small selected areas only and for a short periods. (The EE 4G signals are in the 1800 MHz range, well away from DTV signals.)
If, when 4G starts, you get problems due to the 4G signals, @800 will supply one filter to affected households. Free. Any additional ones needed (?) will have to be purchased yourself, but I'd be highly surprised if you need one.

Rob: Hi Kevin.... Those one for all boosters are not that brilliant. If you get an labgear booster from screwfix they are cheaper than B&Q also alot of aerial installers use labgear for their installs. Now I have to say wideband aerial are ok for middle and upper bands. while London is a the very lower end of the band... Wideband aerials are terrible for covering that end of the band... So if you really want London.Go for group A aerial .. it dont have to be super high gain.... can you tell me where you live again? you can buy them on Ebay under SATAS they do a rang of group A areials in there under Blake and Triax.. around £20 to £25. hope this helps..

Kevin sorry the signal quality is more important than signal strength...... the quality should ideally at 80% that is how i used to set up SKY boxes.... but free view can be abit fiddly you do need a patience of a saint.. have you got a portable tv that you can use in the loft while your setting up your aerial..... it will help you and save you allot of running around...

Kevin: Your booster sounds like its at the end of the chain from your aerial (next to the TV), rather than at the aerial itself. That means your boosting the signal, but also a lot of noise. When you add in your aerial is in the loft, its less than ideal.
Rob is right about signal strength - 75% is perfect, but your dealing with a mixture of geography and physics when getting a Freeview signal, so you sometimes just have to experiment. Loft aerials are even worse, and I'd suggest looking at ATV's excellent guide to aerials, particularly loft ones Loft and indoor aerial installations for TV, FM and DAB - in fact just buy your aerial from them!
Cabling can also make a difference - ATV do very quality stuff for 65p a metre (Satcure does similar stuff http://www.satcure.co.uk/…tm), and of course a good shielded aerial lead makes a big difference - again, don't go to B & Q (ripoff), when ATV does an RG6 cable for £3.
Start with the basics - take out the booster, and see what the signal strength is, then go from there.

Thanks Rob and both Mikes.
I am at GU14 6PW.
My loft aerial has a short cable of about 3 metres feeding the booster/splitter in the loft. So fortunately I am boosting near the aerial, rather than near the TV.
I am not fussed which transmitter I use, but take on board your comments about Crystal Palace utilising the lower frequencies and hence the wideband aerial may not be the best. However, I have since tried pointing towards Hanington and so far all seems much better - possibly due to the higher frequencies used.
There is a Screwfix near my work so I may pick up one of the labgear boosters to see if things are even better.
MikeP - I agree it seems highly unlikely that 4G is the cause of my problems. My understanding is that @800 would NOT provide me with a free filter because I also have Sky. However, since changing transmitter all seems rosy so it is irrelevant anyway.
Thanks for all the comments. I think I am fine now but I may shout if things get worse.
All the best.

in the last few weeks i have had a problem with subtitles. on all itv channels where every 2nd or 3rd line is missing and also some conversations are missed entirely.
bbc and other channels subtitles perfctly its only itv channels. have contacted itv who say they have no problems reported and to switch tv off at wall and rscan if problem persists. i have done this loads of times and also had a tv service man come tound who rest and rescanned yet the problem persists. i have a communal aerial and rception is fine its just the erratic subtitles. dont know where to turn next i need a geek!
