 |
|
I know several RV owners that have placed the ELT antenna horizontally on the aft bulkhead, pointing aft and inside the fiberglass empennage fairing.
I've got the 121.5 version and use a hand held iCom rubber ducky antenna. With both the aircraft and a portable hand held receiver on the ground, I've had good emergency signal reception at over three miles. Not bad reception, IMHO, considering the vertically polarized ELT antenna is mounted horizontally and waws pointing in the direction of the receiver. My set up passed the faa certification process with no comment regarding the ELT antenna.
A friend just mounted a 406 mhz ELT antenna on the aft bulkhead and under the empennage fairing on an RV-8. He used the 406 "walk around" antenna which is considerably shorter than the recommended external aircraft whip antenna usually provided. Bird is not ready for certification yet, but the antenna fits nicely without touching any metal.
