[Antennas] Antenna "farm" question...

When I saw the subject line .. I thought. .good .. another person who is 
going to put up many, many yagis ... then I read your post and smiled.

My rule of thumb is:

Dipoles for harmonically related bands separated as far as possible. 
Those for non-harmonically related bands can be fed with the same feedline.

Vertical/horizontal separation ... as much as possible under your 
individual circumstances .. but .. remember that your tower is a 
'vertical' and, if you're not going to 'shunt-feed' it, then it should 
be over 1/4 wavelength from the vertical antenna ..[I suggest over 1/2 
wavelength].

Good luck
