[aprssig] APRS antenna for an airplane

[w2kb at comcast.net]

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.)
