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. They did it without
asking because it was the right and correct way for the installation.

Well, I consider a "favor" to be something done on my behalf, without
charge.

A $150.00 bill isn't a favor -- it's a charge. And one I didn't authorize.

Still, if the new antenna means 10 years of trouble-free service, what the
hell -- it's only money. But they *should* have asked, first.
