Hi there, I've got a refurbishd unit from Dixons (Nokia Mediamaster, 80 pounds). I live in a really strong signal area, but I have problems when I conect the Nokia box to the aerial cable. What I mean, is that sometimes the box works better withouth the aerial cable. The signal is so strong, that I can view the digital channels using just a 6 feet cable and hold it with my hand. That's how I know that the signal is quite strong. But, when I plug the box to the proper aerial cable, and I check for the signal strength in the menu, it comes as poor. Sometimes it doesn't even get some of the channels. And, I know that the antena works fine, because it improves the image when I use just the TV by itself. Do you know what could be causing that? Could it be the proximity of an electricity cable to the coaxial cable?
