Art, you are simply going to have to draw up your QFH design. In fact,
I believe you have some pictures available now. Failing that, you might
put the URL on the net where most of the information is described! That
antenna is a good one for many reasons. Cliff K7RR

I've seen these ocassionally around the place and I hadnt taken any
notice of them until now when I found the specs. I currently trying to
find out if more of them are available and I'll let the list know if I
get a positive response.

I also am enjoying great sucess with the Transystem and corner reflector from
Bob, K5GNA. I have photos of this set being used from my mobile on my web
page. www.stormchaser.cjb.net click on new mobile and scroll down. This
system is simple to use held out the window of my truck. Bob K5GNA , was super
to deal with. I also got a 2.4 Ghz signal generator from Bob.
