I have an ICOM R-7000 mated with an AH-7000 discone antenna in my attic. I am using the Belden 9913 Coax to connect the receiver to the antenna (Very Low Loss, cable run is about 40 feet). I have noticed that I have never received a signal that deflects the S-meter full scale. The most I see is about a 2/3 deflection of the meter on strong signals, such as local FM stations and local aircraft traffic (I live 3 miles from Dulles Airport). What's more is that the higher in frequency you go, the lower the S-meter reading. 800 MHz signals rarely get to half scale readings. Has anyone else noticed this? Do I have a problem or do I just need a preamp? If so, what is a good preamp to use with this receiver/antenna combination? By the way, I easily get full-scale deflection of the S-meter on my R-71A, my Collins R-390A, but these cover .1 - 30 MHz only. Any comments/suggestions? Thanks, Dennis Gibbs (703) 802-1961
