My book is the 4th edition, so I'm not sure which antenna you have. Is
its circumference listed as lambda/2 or 0.7536 lambda? If it's the one
I suspect (0.7536 lambda) where do you feed it and where does the
shorting bar that you mention go?

Thanks!

Mine is the 3rd edition with Halo Aerials starting on page 7.29. Make
the shorting bar (A) adjustable in distance from the PL259, instead of
brazed to the brass tubes. Adjust for minimum reflected power in your
50-ohm coax.
