Called Rami tech support for advice on mounting location and they were awesome. I like this also comes with a gasket where the comant does not. Awesome antenna.

Q: Hello, Is there a drawing with mounting details available for the Rami AV-74 transponder antenna? The outline drawing doesn't list mounting stud sizes. Thank you, Brian Geiger

Please visit our webpage again and under the documents tab there is an updated pdf with mounting stud sizes and mounting details.

Both versions of the AV-74 support ADS-B. The AV-74-1 is slightly larger and is available under part number 11-13996.

Q: Is this RAMI AV-74 antenna compatible with the GDL-82?

This antenna may work but it has not been tested by Garmin for the GDL 82. Please view P/N: 11-17965 CI-105 which is the same style antenna. You can also view the installation manual for the GDL 82 for more acceptable tested antennas.
