We aren't flying yet, but it would be nice to know your installation. We used all RG400 on al antennas, except for short pigtails of RG58 on the antenna ends of the antennas in the wings (Bob Archer VOR in the right wing and a homemade copper foil glideslope and homemade VOR in the left wing). Both comms have RG 400 all the way. #1 comm is a Bob Archer in the vertical fin and comm 2 is one of his "E" shaped antennas on the right wall of the baggage compartment. You might want to post this on the AeroElectric list for Bob Nuckolls to see.
