Just bought a Wineguard HD9095P (top of the line) and hooked it up to the correct input on the 622. I live about 3 miles form the HD towers but I live in the woods, so the signal bounces around off the trees. Most of the signal readings are in the 70s. I lose the signal often and get pixulation. I think if I put a digital amp on the line it would help. How strong of an amp does anyone suggest, 8, 15, 30 DB? Any suggestions besides cutting a 100 trees? Thanks in advance.
