One of the issues with wide spacing on quads is that they may lose
coupling from the driven elements and don't develop the gain one would
expect. A quagi idea works but that uses a quad driven element and
reflector with the rest of the elements being conventional. I use here a
3 element quad for 20-10 and on another tower I have Hi-Gain 5 element
beams. Most of the time they are equal while listening on a websdr
overseas. There are times when the yagi is slightly better...but only
slightly.

I have been thinking about building a monster quad for 6 mtrs. I have
googled quads and all about but came up with very little data to work
with. I did find a 7 el regular spaced quad on 19 ft boom but I was
thinking of more elements and wide spaced... I have several 44 ft 2 in
booms or even a 60 ft 3 in boom. I wanted to stick this on my rohn 45
at 100 ft. Anyone have any ideas or can point me to a web site or
reflector where i could find something like this? Thanks, Cort K4WI
