Hi Bob

Might be worth downloading and playing with 4NEC2 from
http://www.si-list.org/swindex2.html. This will allow you to model
antennas and check radiation patterns (incl E vs H) with and without
ground and other objects influence. Its GPL.

Also have a look at http://www.cebik.com for a stack of info on modelled
antennnas in the amateur service.

Cheers Bob VK2YQA
