One way to approach this is to look at what successful VHF contest rovers do.
They place the antennas very close to each other sometimes inches.
www.qsl.net/n9rla <http://www.qsl.net/n9rla> has pictures of several rovers
user.adelphia.net/~w3iy/fstack.htm has done modeling of closely spaced stacks.
Some successful vhf fixed contesters also have fairly closely spaced stacks of
For EME, every fraction of a db counts and the above may not be good enough.
