I = mounted the simple strip antenna supplied from with the original kit = from 1987.
I often hear radio transmissions over 150 miles away. = Everyone I have ever asked for a radio check says I am loud and clear.. = The com I run is a KY197.

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
