msoliday Posted February 13, 2023 Report Share Posted February 13, 2023 Hello all I am switching out my sl 40 for sl 30 radio and was wondering what antenna others have used and placement? looks like a RAMI AV-532L will work and seems like installing in top of tail. any suggestions?

Anticept Posted February 13, 2023 Report Share Posted February 13, 2023 On flight designs, they are the these: https://www.aircraftspruce.com/catalog/avpages/comant120200gs.php They are mounted to the tail underfin. There's also a specialized kind of coupler that is used with them. I believe it is this: https://www.aircraftspruce.com/catalog/avpages/comant1203_11-19394.php?clickkey=13230 Unless you are already skilled with radios, I strongly suggest you let an avionics shop do the wiring. You need really specialist knowledge and equipment to install and test radios and antennas. There's very real risk of damaging the radio in the worst case, but more than likely it just won't function right and you'll be pulling your hair out.

msoliday Posted February 13, 2023 Author Report Share Posted February 13, 2023 wow $2000 is a little steep for me. Hope there is an alternative. Thanks! Quote Link to comment Share on other sites More sharing options...
Warmi Posted February 14, 2023 Report Share Posted February 14, 2023 I just removed SL 30 from my panel ( upgrading to gtr 200) and as part of the process I removed nav antenna which I obviously no longer need. I don’t have a Flight Design plane but Sting S4 and antenna I removed was a cat whiskers style antenna ( which is very similar to that Rami you listed ) Quote Link to comment Share on other sites More sharing options...
