Crystal Palace (Greater London, England) Full Freeview transmit
Monday 3 December 2012 11:23AM

Hi,
I have fitted a brand new 48 element High Gain aerial into my loft. I am pointing to Crystal Palace from BR7 6PT. All other aerials are pointing in same direction.

I have a 2-way f-plug splitter just after the aerial serving 2 rooms in my flat using new satellite grade cable.

One TV will only tune into the BBC channels (new Sony) and the other TV (Samsung) will rarely tune to any channels, but occasionally picks up the ITV group. Never gets BBC though.

Someone said to me that my signal may be too strong being so close to Crystal Palace and of course a high gain aerial would not help.

Anyone offer me any trouble shooting please apart from the usual checks of connections etc.

Thanks
Bill

Thanks Dave.
I have looked into the signal levels using the manual tune function on my telly.
CH22 and CH23 are coming through over 75 level and 100 quality.
CH25 wont tune
CH26 is at 60 level and zero quality
CH28 is under 10 level and around 20 quality.

Any suggestions having seen these results? I am using a sideband high gain aerial pointing to Crystal Palace. (51.4529,0.0972)

Thanks guys. I think I may have 'messy' signal. I woke up this morning and BBC, which was up to 100% signal last night, was only at 40% level and under 10% quality this morning!

Is the only thing I can do here, move the aerial? Would it help to swap out the Wideband aerial I got to a dedicated A group aerial?

Dave: Ok I follow now. I was worried the Attenuator wouldn't help having seen poor signal/quality for BBC this morning.

I have a variable 0-20db attenuator ready to go. Fitting is easy, but How do I go about tuning and choosing the right attenuation? Should I start at -20db, do a tune and see what I get?

Also some do and do not allow DC power pass....does this affect my choice of attenuator?
