I have installed all three but prefer the carbon fiber Advanced Aircraft
Electronics (AAE) antenna types because they are "no brainers".
Hey Bud,
I will second that! I have both an AAE Com and an AAE transponder antenna on
N245E and I couldn't be more pleased with them. (and I'm a picky RF engineer
by trade). I've swept the Com antenna alone across the band and the SWR
remains flat at about 1.38 to 1 end to end. I also swept the transponder
antenna
at 1090 Mhz and it shows excellent SWR characteristics, too. The AAE folks
were outstanding to deal with. I originally purchased the Com antenna with a 90
degree BNC connector take off. I decided six months after I purchased my
Com antenna that I really needed a straight BNC take off for proper cable
routing. So, I contacted them and they swapped the antenna at no charge and
even
paid the return shipping!
My AAE Com is mounted on the aft side of the tail post. I made a 1" square
hole in the center of tail post for the antennas connector/splitter assembly
to pass through the tail post, then attached the elements of the antenna to
the rear of the tail post with silicone after scuffing the tail post a bit to
enhance adhesion. The coax feed routes through the center of the bottom rib of
the vertical fin through a small, grommeted hole and forward into the
fuselage. Both transmission and reception are excellent using this antenna
coupled
to a Garmin 250X GPS/Com.
