Antenna wire?
I have a 1986 mini stereo. It plays mini cassette tapes, cd's, has FM/AM radio and is a great little stereo. One problem. The AM antenna is a "wire loop" that works for some of the stations but not ...

First I'm not sure that is the AM antenna you are looking at,, Most AM/FM radios use a "wire loop" (300 ohm folded dipole to be precise) for FM reception but the AM antenna is internal and is a ferrite rod with wire wrapped around it.
Now, that said, you can improve the AM reception.. here is the information you need.
Am Broadcast is the 300 meter band, thus a proper AM antenna is 75 meters long.. Yup that is 246 feet and change.
Take a wire that long (or if you like you can go shorter but performance will suffer) and connect one end to a ground rod, Wrap it twice around the radio and then toss the other end over tree limbs till you run out of wire, hang a weight on an non-conductive rope (nylon/cotton not wire centered) and you got it. NOTE the direction you toss the wire will affect which stations you hear.
I have seen some wire loop antennas for AM though,, Hold on Here are some linke, (Well at least one)

Now I'm not impressed with anything on these links, but the first one MIGHT work. The engineers at MFJ do know radio.
