Good thing you pointed that out Milt!! People were
extrapolating the results to other situations that do not
apply.
It is the ground BELOW the antenna and immediately to the
sides that determines if the antenna will function, and it
really isn't even mostly "wave tilt" on higher bands. Wave
front tilt in the purist sense of the words mainly applies
to VLF antennas.
The Beverage requires loss or imperfect ground below and
immediately around the antenna, in particular for long
distances off the side of the antenna. The distance of
concern is at most only several wire heights for HF.
Let's not turn the fact some Beverage systems work NEAR
saltwater into a "Beverages work well OVER highly conductive
ground" conclusion.
