Antennas
Antennas are matched to a Frequency (band)
What matters is Power Delivered rather than transmitter power
VHF and higher bands operate on the basis of "line of sight"
The gain and radiation pattern of an antenna are critical.

Typical whip antenna radiation pattern
The higher the gain, the narrower the beam

The effect of heel on transmission
