Having said that, I have a FREEVIEW Philips Box on the top of my Video Combi TV in my bedroom,which doesn't run from the main aerial in our loft.
I use an amplified ONE FOR ALL portable aerial (which has a control dial with up to 45dB) and 3x Noise Filter, which I got inside my wardrobe.It's the only place to put it.
Strangely enough with all those great Specs on it, I STILL have problems with receiving a good reception BBC1 Wales,BBC2 Wales, BBC3 and BBC4!!!!!
Some days I get a good reception,then most other days,and usually night times the signal is very poor and I just have to watch another channel!! :(
Oddly enough,when I walk towards the TV the signal improves and the picture is perfect again! How weird is that!
I guess I must be an extra signal booster or something!! Maybe I have incredible static around me.
