Lee,
We probably will just have to disagree about this.
From my viewpoint, the behavior isn't too much different than a big yagi
stack or other antennas we are used to.
The size of the array generally sets the directivity limits. We can add more
elements that are closer-in than optimum, and
Greetings Bob Reflector folks,
Please allow me to provide a bit of my experience since I run both a broad
side/end fire passive 8 vertical array (350 ft diameter) with a DXE
controller AND a HiZ 8 vertical array spaced for 160 meters (220 ft
diameter).
To your specific question about
This thread comes at a good time for me, as I am planning an 8 circle array
as we speak.
My installation will be an 84' diameter circle as I intend to us it on both
160 and 80m. My installation will be in the woods on a rocky hill (New
England glacial moraine). I have found a plateau near the

Thanks for a great post,
Hi guys
I would like to commented on the subject of RX comparison
Tom when you introduced the RDF methodology to measure directivity, you
really hit the nail in the head. I'm working on RX antennas only since 2005,
after hundreds of tests, I am sure that just 1db RDF matters a lot.
When you
Hi Guys,
Excellent point Tom as we will have to disagree on this. I have built both
types of arrays here and like the smaller circle with active elements. I
believe it has a cleaner pattern.
You can see a 3D picture comparison of several arrays at
Joel,
This will be very interesting when you can report some comparative results on
both these good receiving antennas.
I am building - what I believe to be a somewhat novel antenna to try this
season and hope to get it finished in early January.
Maybe someone considering a new receiving
A few comments based on my own experience with various receiving arrays:
Circle diameter of the Hi-Z array:
A circle diameter of 200 feet is specified for the Hi-Z 8-circle array on
160m. In fact, I have found that there is nothing magic about 200 feet.
It happens to be a good compromise
