Crystal Palace (Greater London, England) Full Freeview transmit
Wednesday 31 July 2013 4:45PM


I live at GU14 6PW and have always received Freeview from Crystal Palace via my loft aerial with booster. Recently, I have lost the channels from the frequency C22 and C23 (hence all the BBC channels) although the other 3 (or 4 on the HD TV) are fine. I have tried bypassing the booster and have the same problem. Why would some channels be affected and not others? Could it be linked to some 4G interference?

I appreciate that loft aerials are not the best option, but as I use Sky for 95% of my viewing, I am not keen to pay for an aerial upgrade.

Amy advice or thoughts will be gratefully received.

Thank you.

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?

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.
