Folks
I am experiencing a dreadful time getting my COM radios to perform to their full (or even half) potential in my LNC2. I have two Bob Archer's mounted in the tailcone and in the proper orientation with a VSWR of around 1.5 with RG 400 cable. The antennas are fed by two Garmin 430s with a measured output of 8 watts each. The thing is that ATC and my flying friends report a consistently weak signal and the same applies on reception on my end. My airplane has the carbon tail and I built the seat bench using carbon on foam (bad idea in hindsight). I have tried another type of antenna that is a dipole with a balun mounted in the center of the baggage section in a vertical orientation but with little or no improvement in results.
I am beginning to suspect the Lancair supplied Gray epoxy primer which I understand contains aluminum oxide in the base
I am now considering mounting an external antenna but thought I would ask if anybody had experienced similar issues and subsequently corrected them. Any help/advice would be very much appreciated
Thanks
Tom
