I have a hr24-200 that I am trying to use for camping. I have a older dish 18x20 triple lnb multi-sat that I am trying to use. My question is why am I getting no signal at all? I have it connected directly to the receiver and I know the dish is pointed in the general direction I should be as there is a working one pointed in the same direction. The dish worked fine with one of my SD receivers. Do I need a b-band converter to get any reception at all? shouldn't SD come in at least?
