Does anyone have experience installing an Archer Comm antenna in an RV4 wingtip?

I'm considering the Archer Model 1A and have concerns that it will fit properly.

I bought one each side for the wing tips of my Rocket Jeff, then learned that only one was practical.  In the end, neither was used due to building tip tanks, so both are available for sale.

Usually US$100+ each I believe, but I will part with one or other for US$60 each plus shipping.

Cheers, Stu

Jeff, I have the Archer NAV antenna mounted in my RV-8A's wingtip, which I believe is similar if not identical to that of the RV-4.  So taking your question literally, I would say it will fit OK.



However . . . you didn't ask but I advise against it because of the performance hit of the mostly horizontally-oriented antenna while VHF com requires vertical polarization.



When I ran out of space for vertically-polarized antennas on the bottom of my '8A, I mounted one on the bottom of a wing.  The ground plane is larger and there's plenty of separation for multiple antennas.

I would agree. I have one Archer Nav antenna in each wing tip to serve 2 

navcoms. Performance is okay. While my -10 has big enough wing tips to 

do a vertical com, I wouldn't. A friend put one in -7 wingtip and it was 

good for maybe 20 miles until he had the plane painted with a metallic 

paint. Performance dropped to under 10 miles, so he abandoned and put 

antenna on a convenient wing inspection plate.
