Fred, in terms of angle of radiation versus height, it will behave similar
to a dipole. If you can get it up a half wavelength or higher in the air,
great, but it will work well only a quarter wave off the ground (with higher
angle of radiation). If the ground slopes down in the direction of
propagation, it doesn't have to be high at all. I used it once on a
mountain summit about 6ft off the ground and it worked like gangbusters.
