My zip code is 81401. I am using an Antennacraft
C490 with a 30" run to the plasma tv and a 25" run to the Sanyo tv. I put a quad distribution amplifier from the first run. connected this to the satellite box and plasma tv antenna input. My second run comes out of this amplifier to the Sanyo tv. Originally when I used this configuration I had the NBC channel but it had poor reception. I put a another distribution amplifier at the end of the second run to the Sanyo tv and it gave me excellent reception for NBC channel. Also, when I first set this up with no amplifier the plasma tv only received two local channels that is why I went with the distribution amp. I am not using a pre-amplifier. Thanks for your quick response to my problem.
