    I ordered the antenna kit from Jim Weir and my pops read the manual and installed an antenna.



    I’ve always wanted to better understand radios and I figured this would give me some hands on experience.

    Initial tests are promising but we have some trouble shooting to do. There is a quite squeal and tunnel voice when transmitting.

      Any results on the internal antennas?

        I didn't use my homebrew antenna long enough to form an opinion. The little we did use it I did not notice any issues. No blank spots, no range issues, but we were never far from the airport during the time it was in use. I installed a bent whip while attempting to fix a TX issue but it had no effect. I left the foil antenna in the plane and will use it if I ever install a second com.

          Hey Whee, curious if you ever came back to install that second comm and try out the foil antenna?

            I do not recommend the AAE dipole antenna product. I purchased, read and installed two of them in accordance with there recommendations. One was installed in the vertical stabilizer of the Patrol. The second was installed on the left fuselage on a 45 degree angle. The instructions led me to believe I would have normal reception.

            I had poor to zero transmission and reception performance. Never great (or should I call it normal?) I never had my local control tower give a bad report, but had several from aircraft near me, including one bad report from an aircraft on downwind when I was on the ground next to the runway. I also heard an aircraft at an airport 40 miles away. My confidence in it locally with my control tower was such that hearing them 20 miles out was doubtful. Performance may have been directional in nature.

            After I installed a standard exterior antenna the reception comaprison was night and day. I no longer even think about reception performance. Its as good as ANY new production aircraft.
