hi all, i have my eurovox 2008 maxV about a week and all is fine downstairs but when i hook it up stairs i aint getting all the channels and most of the ones i am gettin have a terrible reception. i know the problem is most likely the signal going upstairs but how do i fix this/where can i buy a better cable? my cable is running through the attic so it will have to be a pretty long one!... ANY help will be much appreciated!!!
