Maybe I have the wrong Aerial then? Is there a particular kind? I've just moved into a new-built house and not sure which kind I have

Hi ABall,

If its a brand new house they often wire up aerial points, but never fit a aerial or distribution amp.

I live at BS20 6QB where the roof top arial can not pick up any digital signal and can not currently be replaced due to an unsafe roof (it is a very old house). In the meantime my portable arial picks up ITV/channel 4/E4 etc fine but no BBC?

Ed: You are probably picking up from the Ridge Hill transmitter then, which has not switched. If you must try an indoor aerial, put it as high up in a window as possible, hopefully pointing towards one of the high-power digital "switched" transmitters. See Find out how to receive Freeview and Freeview HD | - independent free digital TV advice please.

I live only 100 yards or so from Redcliffe Bay transmitter and yet we are having digital breakups when watching a recording of Channel 4+1, this has happened a number of times in the last few weeks...we were told that when it went digital and we could get a signal from our local transmitter (rather than Wales) all would be OK !, what is the problem?.

PS: we watch TV via Freesat dish, but our recorder is through a roof ariel.

Gordon Comley: The most likely explanation is that you have too much signal. If you have a booster, try removing it or turning it down - if that doesn't help, remove the booster and try adding an attenuator.
