As far as a vertical mounted on solid rock, ever heard of
radials? Almost all analysis shows angle lowering by copious
addition of radials to a vertical. I suggest You find the QEX
articles written By Rudy-N6LF which studied radials
thoroughly. Even with very short radials my 630m inverted-L gets out
over 2500-miles (at times0.
Another antenna I discovered that I really liked is the Moxon. I has
the gain of a two-element yagi but works well in almost all
directions (point it toward your favorite direction). I ran a 6m
moxon at 0.7 wavelength height in CO during a contest and worked all
four borders of the lower 48 states using 150w. Worked quite well
without turning it (pointed east).
At home I use an inverted-V with center at 40-foot and tails at
20-foot. Works out to 800 miles very well; works West Coast
(3000-miles) from AK in BP40 with 100w.
