Having recently been car shopping, I've noticed that radio antennas
have changed again. My old car had a retractible whip antenna that
went up when the radio was turned on and down when it was turned off.
I had to replace that once in the life of the car, and it was
already not going down all the way again.
I notice that a lot of newer cars have a small antenna, about six to
twelve inches, above the rear window. I wondered whether that would
be sufficient for decent reception of AM and FM stations, but when I
tested this on cars that I test-drove, it seemed to work. Why is
this antenna adequate? Will it also work for satellite radio?
Other cars have an antenna embedded in the rear window. I had a 1977
Oldsmobile that had the antenna embedded in the front windshield. I
suppose embedding it in the rear window is about the same thing. The
antenna looks like a typical FM dipole. Why does this work for AM as
well, as it does seem to?
