[Antennas] Antenna "farm" question...

[Gene Buckle]

Hey folks, I'm in the envyable position of being able to put as many 
antennas as I want up, with 2 acres to spread 'em around. :)  My problem 
is that before I start spending all the time to scratch build a series of 
band specific antennas, I need to make sure that they're not going to 
electrically interefere with one another.  

Is there some rule of thumb that dictates physical spacing of installed 
antennas?  They'll be a mix of Dipole and Vertical antennas.  I only have 
one small tower so I may have a small Yagi as well.

Thanks all!
