Jay, They did you a BIG favor. You should tip them for being pro-active on
the maintenance on your airplane. Everything on an airplane wears out, and
a
transponder antenna is right up there on the list.

Please explain how an antenna wears out.

They crack, get dirt in internal connection, etc. Check out the
www.avionicswest.com for some other examples.
