1) See a text on antennas and bring your math. :)

2) Plug the problem into modeling software like NEC, making some 
rash assumptions about the nature of your ground. 

3) Build the antenna and measure it.

#3 is most likely to give you the best answer, but if you have time 
on your hands, give #1 or #2 a try. :)
