What COMM antennas are pilots using on the belly of the RV-8.
Background:
I am having a "weak reception" issue with my Garmin radio (GTR20) in my RV-8.
I've had the radio and antenna checked for power output, frequency accuracy, and SWR. All are good.
My COMM antennas are mounted in the usual location - under the pilot, just aft of the main spar.
My radio calls are being heard by other airplane's and by the ground stations - eg Aproach / Departure control. However, I do not hear the ground stations unless I am within at least 20nm and sometimes closer. It varies but in general, i need to be closer than I would expect.
If I open the squelch, I do hear the response from the ground stations and it is faint.
