Hi Paul, 

Its the perfect location for a Topband 4-square array! 
It would be even better if the array were in the marsh... 

Marshland Road,
Hilton Head Island

Is there a Marshland Road on the Maine coast?

Rich, 

Have a look at 1KW 1130 AM on Hilton Head Island, SC (WHHW-AM). At 12 noon
on any day, I can easily ride that signal down the Space Coast of FL and
about 10 miles inland. That's the entire coast of GA, part of SC and half of
FL.

Below is a link to the groundwave field of a 1 kW non-directional AM
broadcast station located about 1 mile from the Atlantic, in Florida. 

The groundwave field shown is based on the FCC M3 conductivity map, and
their GW propagation charts for this frequency and power. 

The space wave fields radiated by vertical monopoles are related to their
groundwave fields, so space wave fields radiated over (mostly) salt-water
paths are much greater in magnitude than over terra firma (other things
equal). 

Maybe this will give a rough idea of what to expect from a sea-coast QTH in
Maine.
