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?

I'll give you one anecdotal data point. I bought the $22 "TED"
transponder antenna from Aircraft Spruce a few years back. It seemed
well constructed and my transponder signal is apparently getting out
as I've had no complaints of dropouts from ATC.
