OK, I'm not getting a redirect. But the page that shows gives pretty good information on building a basic FM dipole.

Some further points:

If your radio has a coaxial connector for the FM antenna, a simple dipole will match the radio better than a folded dipole. A folded dipole will work OK but a simple dipole will transfer a little more signal.

The length of the dipole isn't supercritical. A few inches one way or the other doesn't make much difference.

The dipole will work best if it's kept in a straight line.

If you're in the US, most FM broadcasters are transmitting a circular polarized signal now. This means that the receiving antenna can be horizontally or vertically oriented or anywhere in between and still work.

If you want to try something quick and dirty, put the bare end of a thin wire about 5 feet long into the center terminal of the radio's coax antenna connector. This is hardly ideal but it's easy and might work well enough.
