On one of my $100.00 hamburger flights my VOR-Glideslope went in op.
Worked fine until I landed then at take of it would not register. I
visually checked the antenna, but every thing seemed to be OK. That
afternoon I flew to my avionics shop for a check up. Of course my
plane is due for the 24 month Static check in June. Any ideas what
could have caused it and ballpark on cost?

Last week mine died in a similar circumstance. It worked perfectly one
flight and was absolutely dead by the next. No warning at all. It turns
out the wiring harness simply came unplugged from the back of the
indicator.
