Brief Description: Mounting ADS-B Traffic And Weather Antenna
I finally decided to start on mounting antennas. Started with the RAMI AV-74 blade antenna for the ADS-B Traffic and Weather receiver. This is to be belly-mounted, with no metallic protrusions within 18", and at least 2 feet from the transponder's AV-74 antenna.
Don't ask me how, but I managed to totally disregard the lading gear leg being only 5 inches from the antenna on the belly. IMMEDIATELY after mounting the antenna, it slapped me in the face as I looked at it.
I spent a couple phone calls and emails to R.A. Miller (RAMI) to explain the situation and provide some pictures. Their tech support folks assisted me in identifying better locations for these two AV-74 blase antennas with no further impact on the other three remaining antennas that still had to maintain their separations as well. I went from mounting the two AV-74 antennas side-by-side with 24" separation, to in-line on the fuselage centerline with 24" separation (the transponder antenna was originally going to be a mirrored mounting on the other side).
I also templated a doubler plate for the AV-74, to mount on the inside of the belly, even though it looks pretty stable just mounted in the skin alone.

TOTAL lack of attention to the fact that there are not supposed to be metal protrusions within 18".
