I'm not an antenna designer, but I can tell you that the M2 LEO Pack crossed yagi elements go through the center of the boom (i.e. across the radius) and are insulated from it. They don't contact each other because they are offset from one another along the length of the boom. Of course the phasing lines have to be adjusted to deal with the elements being offset.
Is that what you mean?

I'm sorry, but I wasn't complete in my description: I'm talking about yagis with the elements completely isolated from the boom with saddles (clamps) mounted on the boom to hold the elements in place. Much like the original LFA yagis are build. For an image go to my blog at bx2abt.com. --Hans

Should the elements of a RHCP cross yagi be centered at the boom, or should they be off center so that the middle of the H and V elements cross each other in the middle? My gut feeling says off center, but I'm not sure. I wonder how this influences the SWR. Cheers,
