While this antenna undoubtedly sucks for what the typical amateur wants from
HF, it seems perfectly suited for what the military mostly used to use HF for -
tactical regional communications over a comparatively short range - 50 miles or
thereabouts regardless of terrain. Frequency agility and broadband utility are
more important than long range, which is essentially irrelevant given the
application.
AFAIK, satellites have taken over this application space.

Hi Michael,
Beside my opinion of the Barker & Williamson antennas in general, a leaky dummy
load, I used something similar during my service.
I don't really understand how you set this up but it appears as you put the
ends of the antenna on 9 foot poles. I believe the intention is that the ends
should be placed at ground level. You could probably pull a wire between the
ends (kept at the 9 foot level). That would give you the half rombic back. (I
believe this antenna is suppose to be a half rombic).
A second attempt would be to place the ends on ground level. I don't think the
angle of the top is critical as long as you keep it decently close to the
suggested by B&W.
Good luck and keep us informed how you solved it.
Best 73 de,
Hans - N2JFS

Subject: [TowerTalk] Barker & Williamson Model AC - 1.8 - 30 Antenna
I recently installed a Barker & Williamson Model AC - 1.8 - 30 Antenna. I
installed it as a sloper following the manufacturers instructions. The top of
the sloper is mounted on a tower at 50 ft. The opposite end of the antenna is
attached to a post 9 feet above the ground. At this location, the antenna is
grounded with the counterpoise. The other end of the counterpoise is not
grounded at the opposite end ( at the tower).
PROBLEM: I can not get anywhere near a descent VSWR using a IC-756 Pro III.
Please get me some suggestions to solving this problem.
I have photos if desired.
Thanks to the TowerTalk users for their help!
