Yes, you only need a directional antenna. There are a myriad of solutions
available.

First FM is a modulation method, not a set of frequencies.

What frequency are you interested in? A little more data would enable the
newsgroup members to help you.

I am interested to know if there is a way to transmitt FM radio
frequencies
in a directional path. I need to transmit from 1/8 to 1/4 mile in a very
direct narrow pattern. Does anyone know if this is possible.

If these are 3-meter band (100 MHz) signals, a dish to confine these
frequencies directly to a small beamwidth (20-degrees) is impracticably
large (about 30 feet in diameter). Likewise, a Yagi to confine beamwidth
to about 20-degrees is about 20 meters (66 feet) long.

The best way to reach 1/8 to 1/4 mile with a narrow pattern may be with
a wire or cable of either electrical or optical type.

If 100 MHz is the information signal, it can be the modulation on a
carrier frequency in the microwave range which can be directionally
confined with reasonably sized antennas, or the signal can be modulated
by digital or analog methods on an optical laser or led circuit which
confines the beamwidth to a narrow beam.
