My own design of installing a Intenna for the FM for radios that have a broken antenna. That's upside down Notice the white wire which has been installed in place of the external antenna which is now what I call the Intenna. You got bonus points if you know what model this is lol.
Makes sense to just put an internal wire antenna like that for FM. Though for authenticity on old desirable models one can get sorta get various "close enough" replacements on e-bay if needed.
Nope, I checked that one takes a very specific size and so it's included in the end bag if you really want to get that little piece spot welded on to its specific bracket. Otherwise just deal with it. Having an internal antenna and giving you stereo sound anyway. I bought a few and I have a few so none of these work.
I'd love to be able to make antennas, I think I posted a video in the video thread of a small Asian Shop making them.
