Poor TV reception on Bedroom TV

[nelsonraymond]

Hi
I was wondering if anyone else has had problems with their Tv reception since using converter box for digital? We get 3 channels in Bedroom and 16 in front room. Sometimes non in bedroom. We added that wingard adapter for uhf but that did not help. Is the only solution a new HD TV or is it the way it is wired?
As it is we have two converter boxes, when watching TV with one on you can't watch the other TV at the same time seperately with the other box on. I can put the box on in the living room and transfer the tv to the bedroom but then I can't change the channels in the bedroom. That is why I hooked up the other box on the bedroom TV. Something doesn't seem right that youcan't have both units on seperately?
Can anyone help that has coverter boxes?
