This is not exactly the answer, but it should help you think about it.

Also, if the land around you is not flat, you also need to study and use 
HFTA extensively. It comes on the CD with the ARRL Antenna Book. HFTA 
tells only about horizontally polarized antennas, NOT verticals, because 
they interact with the earth very differently. The slides tell a big 
part of that story.
