Folks,
The Garmin GNC 255A nav/com in our RV-6 has never worked quite right. The comm side of the radio works great, but the nav side doesn't seem to receive anything. The radio functions properly, but it can't receive a VOR ident and won't display a bearing even within a few miles of the transmitter, so I'm inclined to think that I have an antenna problem.
I installed a fancy Bob Archer antenna in the fiberglass left wingtip fairing. A photo of the antenna installation is below [note that I inverted the wingtip fairing and placed it on the wing. The antenna is mounted on the inner-upper surface of the fairing]:
So, is there anything evidently wrong with this? Do any Electrical Smart People have suggestions for further troubleshooting?
It's a pain to pay so much for a radio and not be able to play with it...
Thanks,
