Hello John, LF group,
Thanks for your reply. The pickup loop is
basically as you described, but with a
slight difference. The feedline comes to the
bottom of the loop where the shield
is exposed, then continues around the frame to
complete one turn. At the end,
both the inner conductor and the shield are
connected to the exposed shield
where the feedline/loop transition
is. There is a half inch gap in the shield at
the top, directly opposite that connection, which
stops the shield from being
seen as a shorted turn. I'm told that another
feature of doing it that way is
that it forms a built in balun. I was
striving for symetry.
Thanks & 73, J.B. Weazle McCreath, VE3EAR -

The clamps are in the wrong plane to present a
short, so don't worry about that. Describe the connection of the feedline to
the RG-213 link, please. I'm guessing that the coax feedline comes to the
bottom, continues around to form the loop, and then the center conductor
attaches to the feedline shield at the bottom, with no shield connection from
the end. Sound right?
