Interferences with the antenna? (Nokia Mediamaster)

[Gades]

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?

A nearby analogue channel or the multiplex itself could be overloading & desensitising the tuner if it's so strong that you get results with no antenna .
Buy or borrow an in-line attenuator or 2 & see if this cures the problem.
You could do with the loan of a couple from a local friendly aerial rigger - perhaps on a promise of purchasing them if they cure the problem.

Thanks Chris, I'm not sure what you mean, but I guess they will
