Recently I had to swap out my HD receiver for a H21 because of issues it was having. This is setup in my bedroom and I have always been able to hide the receiver and control it with the RF antenna and remote. The H21 has the built in RF antenna, but the range is what I am having problems with. I am about 8 ft. away from the receiver and it rarely works. I was not expecting the built in antenna to work as good as the external one that my old receiver had, I used to be able to control channels from the next room on another t.v., but it pretty much defeats the purpose of the RF capabilities the way it is working right now. Any advise would be appriciated.
