Personally, I don't understand all of the fuss about HFTA. In the general case
(sans 200' towers), aren't you pretty much stuck with your environment with
little to do about it?
But regarding the benefits of saltwater locations, I wonder whether they are the
result of lower angle radiation peaks or simply the increased efficiency of the
ground plane. In this query I'm considering 80-meters and more particularly
Topband, where higher angles that get through the E layer quicker can be beneficial.

This analysis of an 80m vertical over sloping ground certainly shows that a
significant low-angle gain benefit of up to 11dB over a flat terrain vertical.
I include a comparison to other plots from Johns book showing how a vertical
over saltwater shows a similar outstanding low-angle response, which we have
all heard in action from various well place DX-peds on the saltwater. I
extrapolate this to 160m.
