Antenna heights are insufficient for

distance. The combined antenna heights
would need to be more than 400 feet for
marginal line-of-sight communication.



I agree with Chuck. Marine radio is useless over-the-horizon more than
5% of optical line-of-sight.

Contact your local 2-way radio shop and ask them about installing TRUNK
RADIOS in both the shore installation and on the boat. The trunk radio
systems use very-high-up digital repeater stations that are widely
interconnected by computers that talk to the trunk radios, not unlike
what a Nextel iDen phone does, but on a much more powerful scale. These
trunk radio systems are shared by many diverse users, who rent service on
them for a pittance of what the entire trunk radio system costs.

Look in your local phone book under "2-way radio" or "trunk radio
systems" or "radio communications".

Professional communications, especially where life and limb might be in
danger, is well worth paying for. It's why the cops all use trunk radio
systems!
