[Antennas] J-poles

[Buck]

Do you have a diagram of the antenna and how you make the connections?

Thanks

With due respect to all concerned, I don't think
the author give any consideration that an antenna
such as an end-fed 1/2 wave can be voltage fed,
not current fed.  The Zepplin antenna was a 1/2
wave wire fed with a 1/4 wave, or odd multiple,
open wire transmission line.  The transmission
line didn't have to be 1/4 wave, but it had minimum
voltage at the transmitter if it did.  I make J-Poles
that don't use the feed coax as a radiator because
the overall antenna is designed like a Zepp.  The
coax shield connects at the bottom, not some place
up one side.
