I have a Garmin 296 which I use in rented C152s and C172s. I don't use an
outside antenna. I just put the GPS receiver on the dash of the aiplane (on
a beanbag mount, which is temporary and works great) and use the little
antenna on the GPS receiver. It works fine. I've never had any problems
with reception.

Looking ( yeh I know I have been looking a lot) at buying a Garmin GPS (
probably a 96C), and they have 2 types of external antenna, one has like
a
suction cup on it and the other has a magnet.). Just wondered what type
is
best and where the best place is to locate the antenna . I would have
guessed the back window would have the least obstructed view, but then I
have to run the cable from the yoke to the back window which sounds a bit
messy. Will the front screen be OK? ( I am only a renter, so I cant lay
any
cables permanently). What do other folks here do with their antenna? I am
a
bit wary of the magnet idea in case it affects the compass ... I dont want
to rely totally on GPS.
