Topband: Circle arrays

[Tim Duffy]

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.
