Was a direct drop-in replacement for my old Narco mono-pole antenna with quick, easy installation. Bonus is supporting a local USA company (RAMI is here in Michigan). Have yet to fly with it so no pirep on performance. Delivery via USPS was as quick as can be expected, especially during Covid slow downs.

Q: Is the RAMI AV-22 compatible with the Garmin GTX-335? Looks much better than the big, white, and expensive Garmin GA-35 antenna.

This antenna does meet the requirements per the GTX installation manual. However, if you are interested in the GTX335 with GPS you will still require the GA35 as that is a WAAS GPS antenna. The AV-22 and the GA35 are not the same antenna.

Q: Will this RAMI AV22 work with the Garmin GTX345? Neither it nor the CI-101 (which it says its a direct replacement for) are in Table 3-7 Acceptable UAT/1090 Antennas from the Garmin install manual.

You must use the antennas that are listed as a compatible antenna. The CI-105 is listed and will work. 11-17965.
