FM band lies between 88MHz and 108MHz. Most often used antennas in this band are dipole or some variant of it, and higher gain is achieved by vertical stacking. Polarization used is vertical or circular. We will be describing vertically polarized dipoles only.

Indoor wire dipole antenna 72 Ω

For receiving only, we will choose 100MHz as our target frequency as it will cover all the band.
