Thanks Hyundai tech. The FM is doing well, so I doubt the antenna has a bad
connection. It looks like I'm going shopping for a radio. I live news,
sports, and talk and its located on AM.
Hi, Just a quick question. I, too, have noticed a loss in AM
reception. If the antenna is the problem, will it make a difference in
reception on AM, even with a new radio?

The problem is more likely to be that the radio has a poor quality AM
tuner section. One possible fix might be to buy a better AM radio (not
necessarily a car model) and patch it into the existing antenna with a
splitter.

A bad antenna will affect any radio to which it is connected.
I wouldn't give up on the radio if it hasn't been checked. I suspect
you're right, but putting in a new radio if the antenna is your problem
won't improve anything. Although counterintuitive, I've seen the loose
antenna wire cause a major problem on AM but almost none on FM. GM had a
problem with antenna wires pulling apart on some of their late 90's N-body
cars that would cause the exact condition you describe.

It's not counter intuitive. The frequencies involved are quite
different - roughly 1 MHz vs 100MHz. The higher the frequency the
shorter the antenna. A broken stub might well work at 100 but be way
too short at 1. AM car radio antenna length is way short to begin
with but is compensated for with circuitry in the radio.
As a quck check I would connect another car radio, tweak the AM
antenna adjustment and try it in the car. YMMV. ;-)
While I am at it - Unless one is looking at high dollar specialty
communications gear it is unlikey a non car radio will have the noise
suppression and proper antenna matching to work in a car.
