Still looking to improve my flarm range especially below. I have a Trig T22 fin antenna on the bottom of my 27. Can I somehow incorporate the receive only flarm antenna into this fin? Too close to the transponder?

RF engineers speak up!

Thanks, Matt

I'm not an engineer, but have dealt with enough low-powered RF around the World to suggest... Don't do it.
Is your 27 a B model? If not the FLARM and PCAS antennas can go forward of the rudder pedals on the sides of the nose. Peter Kelley published the installation for his 26 and I used that location in 27058.
