    take a look at this:


    It seems that the antenna in this circuit that I got off the web is made as an inductor with a bunch of twists.

    Shouldn't an antenna be just one long wire coming out of the receiver?

    Ive seen a circuit for an FM brodcaster that uses a wire like that as a variable capacitor. You use it to tune it. I see if I can find it.
