[SCCC] The Moxon Claw antenna

[Clayton Nall]

Hi Folks,

With all the years of experience here in the contest club, I'm wondering if
anyone's had experience building or attempting to build one of these
antennas, which may be Moxon's most interesting antenna design.  As far as
I know, the only person who is using and evangelizing the antenna is VK6PH.

It's a fascinating design that allows instant beam heading reversal and one
of the interesting features is that you can, in theory, adjust the antenna
to give maximum gain on transmit then maximum F/B on receive.  It also
offers continuous frequency coverage and gain from 20-10M.

On 20M, the current is at the top of the antenna, so the effective height
is well above mast level.  Good for people with less ability to put
antennas on high towers.

I can see how lots of folks would just settle on an easily built Hexbeam
instead of trying to homebrew this.  And, obviously for contesters, a major
limitation is that it's not a duplex-able tribander for SO2R.
