Not familiar with ur receiver at all, but when u say can only get quality on C-Band Sats, is that using the same 36 " Antenna and same receiever?I've tried all the different settings on the receiver but only seem to be able to get quality on the c band sats with other dish setups
Seems hard to believe u'd get C-Band on such a small antenna and not Ku Band. Perhaps you might have some Band Switching issues? How do you switch Frequency Bands? How many Coax cables enter the home?
If one Coax for each frequency band, perhaps you have a bad Coax cable in ur system?
