A jpole is a end-fed halfwave - and because of that, lends itself well to
vertical applications.
It could just as well be oriented horizontally,
but
for a half-wave horizontal antenna,
a run-of-the-mill center fed dipole may be in order.
feed it directly with coax from the transmitter.
or not
(long runs may deserve twin lead or ladder line)

I'm interested in a wire gain antenna for 6m SSB, and the design above
looks like a pretty quick project. Is it possible to use a j-pole like
this above efficiently as a horizontal antenna? Couldn't it be
center-fed with, say, 2 collinear half-wave sections seperated by 1/4
phasing stubs? In doing so, I was thinking of feeding the center with
300 ohm balanced line.

Thanks for any thoughts.
