off the top of my head, looking at the article, i think there's an
error. he says EACH antenna needs to be 12.4 feet above the surface,
but i think the SUM of the antenna heights needs to be this...IOW each
antenna needs to be 6.2 feet high.

If two vessels are ten miles apart, they will each
need antennas 12.4 feet high in order for their
radio horizons to be in view (line-of-sight) of
each other.

why is that? the equation sez 12.4 feet for antenna height. does that
mean 1 antenna could be on the ground and the other at 12.4 feet?
