I have recently installed a Freeview box (Sony) and its great. All the BBC stations are fine and clear but all the ITV ones are received poorly. I think it is the ones on Mux2. Some radio stations are also poor. The freeview postcode checker says my area (Battersea) should have perfect reception. There is a 5m arial cable that goes from the Sony freeview box to the wall socket but it doesn't go near any other wiring or power points. I live in a block of flats about a year old and the building is supposed to support digital TV and Sky. What can I do to improve the signal???
