OK using this image as a reference,
Ok the yagis are 8 elements on 2 meters and 21 elements on 70 cm.
Similar boom lengths.
Now when vertically polarized and stacked side by side as in the top
picture how close can they get to each other before starting to mess
with each other.
Same thing in next image but horizontally polarized so above and below
Now if they are 90 deg in rotation IE: one is vertically polarized and
the other horizontal, I'm thinking they could even be on the same boom
So that brings in the third drawing same antennas but at 45 deg to the
horizon but 90 to each other, How close can they get without bugging the
Now with the 45 deg angle thing, how much will a metal cross boom mess
