There IS a gain somewhere between 10 - 15 dB next to, or over salt water with
vertical antennas as compared to similar antennas installed inland. Jump in
the mobile and drive around you WILL see it! Even modeling programs show it.
Numerous factors come into a play with salt water front: better "ground"
improves efficiency of the antennas, huge "ground plane" brings gain at very
low angles (Brewster), unobstructed plane horizon and no noise generators out
there (except sun).
