Review of excellent portable antenna

[Tony Estep]

Apropos of the OCF conversation, and considering that Elecrafters are
lovers of portable operation, there's a very interesting review of the
Bravo portable vertical antenna in March QST.

The antenna is designed and produced by N6BT, the guy who built and
later sold Force 12. It looks like a ground plane, with a vertical
radiator and radials, but actually it's a clever adaptation of an OCF
doublet. Quoting from QST: "..the 'radials' aren't ground-plane
radials in the usual sense. An evolution of previous N6BT vertical
dipoles, it is an off-center-fed configuration with the lower half
split into two radials...."

The review, written by Ward N0AX, is very favorable, and concludes "I
have used [long list follows] and this one is by far the best I've
encountered..." If you're interested in portable operation, or you
just want to see a clever antenna design, check it out.

The Team Vertical guys have used these for a couple of years on the C6
CQWW operations. Very easy to set up and tune. And world record setting
efforts too! Here is a picture of one, maybe a little bit too
aggressive, installation.

Very interesting, Fred, thanks. I didn't know that -- just thought it
was a cool implementation of the OCF concept after all the confusion
from the previous thread. I'm hoping to operate portable this Field
Day with my KX3.......
