         I've used an HT with a rubber duck to check into a repeater net 
200+ miles away, so you'll be able to get SOME results with almost anything.

         The suggestion to use an inspection panel is a good one, but if 
CASA is a problem, you could simply have another aviation antenna added and 
use that.  It would help if you could get it tuned for 144 instead of 120, 
but I suspect it would work in either case as long as your transceiver 
could tolerate the mismatch.

         BTW, if you normally fly pretty high AGL, then mount the antenna 
on the belly.  However, if you normally fly low, like a crop duster, you 
might be better served by mounting the antenna on top.
