Yes but it needs to be a mono jack with two conductors tip and barrel.

Connect the wire to the jack tip for a single wire antenna.

I guess you can't just use any end, I used one from an old pair of
headphones that broke for the heck of it to test and it barely got
any signal in. Am I wrong about using copper wire like this?

If you want something better use two wires, one to the barrel and the
other to the tip. Stretch the wires in opposite directions and you have
a dipole. Make sure they don't short to each other inside the jack.

If it ever gets a short, it will not damage the radio, at least
permanently right? I mean since it's not like electricity going
through or something, right?

The jack is meant to power a small external antenna amplifier that Sony
sells so don't short the two contacts in the jack.

Though, will it ever damage the radio?

I don't know if the voltage source in the radio is sufficiently self
protecting or not.

Isn't it true that if there is noise, that a better antenna will only
make it worse? Odd thing I have been noticing with the dipole antenna
is, on 6000/6180 RHC, I can hear the music and news fairly clearer
then the whip all the way up and a fair amount louder but on a local
MW station, that always seems to come in clear on any AM radio,
actually seems to get quieter and appears to have more noise to it.
Also, do I need to worry about the length of the wires? I read a
couple websites on dipoles and they say it's to be 1/4 of the
wavelength that you want for the meter band, but I don't want a
specific meter band, I want to do just general SW listening, and I
have stations all over the place.
