By design FM transmitters are not designed to go very far. Antenna
will
not help.

ONLY AM, SHORTWAVE, SSB, and MICROWAVE. The 2 Meter can go far because
of
the repeater station, but that's a different story.

It's not the way the transmitters are designed, it is the behavior of the
earth and its atmosphere at those frequencies. The transmitters are
actually very powerful.

If your logic is true then why FM cannot defeat other modulation?
Assuming
they all have equal RF wattages?

You're not expressing yourself very clearly. "FM" is both a modulation
technique and (in much of the world) a broadcast frequency band.
Propagation is largely a matter of frequency. It is true that FM does not
perform as well with weak signals as AM, which in turn is not as good as
SSB.
