Unless you want to redesign the antenna's taper schedule, I would simply
get a piece of 1/4" tubing and place inside the entire length of the
3/8" tip section. Then I would use 3, 4 or 6 top wires - make them 18
or 20 gauge for strength. Arrange them equally around the vertical and
clamp them to the tip section with a SS band ("worm") clamp.
Since the 3/8" section is only 36" long (only 24" exposed), I would
strongly consider attaching the top wires at the junction between
the 1/2" and 3/8" sections ... at worst the top wires will be 24"
longer than they would had they been at the very top.

26 gauge wire. Using this method, I think a hairpin loop at the base of the vertical will
help me achieve resonance. Thanks again. Dick W5AK
