1/2 wavelength on the higher frequency band is normally all that's required for
stacking horizontally polarized yagis.
That would be a mere 40" between 6m and 2m, and only 13-1/2" between 2m and
70cm. More is great, but this is about all that's needed.

Subject: [TowerTalk] VHF/UHF Yagi Separation
Hello, Firstly allow me to say what a great group of guys and Gals, we have
here in the forum, all the wealth of knowledge and wisdom I have picked up by
such a breed of fine individuals should help me some day return the same
knowledge to some new comer of this hobby we call "Ham Radio"
Ok now that my brown nosing is out of the way, its my turn to pick the great
minds here...
I plan to put 3 yagis on one tower, one yagi is a home built 19 element with a
corner reflector for 440 Boom length on this puppy is a mere 8 feet. Below that
yagi I plan to place a 8 element 2m Yagi with a boom length of 14 feet and
finally I have modded my home brewed clone of the Cushcraft A505S boom length
is some 17 + feet. Now my question is what should I have both ideally, and
minimally for spacing's between each yagi, feel free to reply either on or off
this reflector, I personally hate it when it is done off the reflector it helps
others at the same time , so do what ever pleases you most.
