As Ken mentioned, height is an important factor in a horizontal or semi-horizontal antenna. There's limited "gain" in any direction at low angles unless the radiator is 1/2 wavelength above ground. That's why most of us have to live with little directivity on the lower bands. The option is to con

I certainly second Geoff's suggestion of EZNEC. While I'm wary of modeling programs in general (remember, "garbage in, garbage out"), I use EZNEC to give me a "feel" for what can be done in a certain set of conditions and to draw a general idea of whether a design or change is likely to be worth
