I'm starting the fabrication of a new boot cowl for the Champ project. The
transponder antenna got wiped off the bottom during the groundloop (no, I
didn't do it!), so I gotta get a new one.

I've seen the 'bargain' version in AS&S for $22 or so. Are they useful, or
should I spend the ~$60 for a decent one?

Anybody have one laying around that they no longer need?
