HI Dave
There is no doubt that a diversity setup with good Beverages and the 160 meter
optimized 8 circle from HI-Z will be a killer RX system.
Lots of work - but very worth the effort.
I LOVE my HI-Z 8 circle!

That is the crux of the situation. I am not so interested in other
bands but was wondering how much I would lose on 160 with a multi band
design. I don't want to lose much at all!
My brother who is a ham thinks I am crazy to even contemplate a circle
array. My goal is to use the circle array as a diversity antenna with
my beverages used on the other receive channel. I believe it will be a
good choice. He thinks my beverages are just fine, but I believe that a
diversity setup will be a big jump in performance. I sure hope I am
right!! It is a lot of work.
