I would want to know a lot about how you adjust the phasing to use this
setup on more than one band. Theoretically you can get a cardioid pattern
out of two elements with the proper phasing lines, but then you have to
switch them around for a cardiod in the opposite direction, and have yet
another phasing arrangement for a figure-8 pattern broadside to the array.
And that's just to make things work on one band. I think this is more
complicated than what you want to deal with. We are probably not the right
folks to answer all of your questions about this. If you could actually
read the ARRL Antenna Book, you could begin to get an idea of what is
involved.

Subject: 2 element phased arrays
Hi all:=20
Anyone got any experience or knowledge of 2 element phased arrays?=20
I'm considering adding another zero five 43 footer for phasing and I was =
wondering,=20
if I had an element pointing to both the short and long paths, would =
there be a little gain and better receive opposite?=20
I'd place 1 element in the NW direction, 1 in the SE but if I'd wanna =
work state side, I'd have to look SW but wouldn't have an element there.=20=
I'm looking into the W9AD system which is a multi band set up.=20
Oldman Winter doesn't like 40M yagis up here and to put up 1 that would =
last, I'd be looking at a cost of about 3000CAN and that's if I buy a =
used heavy duty tower on the used market, new rotator and mosley 2 =
element 40M yagi.=20
I could probably do my 2 element vertical phased array for that and I'd =
have gain on 75M as well, plus can lower them if a big storm blows up.=20=
Can't really do much with a 2 element 40M yagi at 60 plus feet except =
pray. LOL=20
