If you are really wanting to "build" something here's a reference that has some pretty basic stuff and is oriented to the VHF and UHF spectrum. FM is at the low end of that frequency range.

Don't try to use "logic" when working with antennas. There's a lot that seems to the layman to be "black magic." In reality there are issues of maximum signal transfer and impedance matching.

Yes, random wires, single strand wires and the like will sometimes work if you're lucky. The easiest antenna to make is probably a folded dipole out of 300 ohm twin lead.

Remember though that a low elevation dipole that you're making receives from two directions and to get decent gain and a strong signal you need a beam/yagi antenna that concentrates and narrows the pattern to one direction.
