Take a look at some of the Omega antenna installations.  They're 
designed for decent radiation efficiency at around 10-15 kHz.   One, 
in  Norway, had the topload suspended over a fiord, with the vertical 
element hanging down.  Your 2/3 mile secondary height isn't far from 
the dimensions of these things.

There's also 2000 ft high TV transmitter antenna masts around.
