A previous owner of my '76 Cessna Cardinal had an extra aircraft antenna mounted on the belly with a cable terminated with a BNC connector in the cockpit so that an aviation handheld could better be used as a backup should both the regular transceivers fail. I recently tried the antenna with a Kenwood D700 running at the lowest transmit power setting and it works fine. (I don't want to trim the antenna length to better preserve its backup use.)
