Thanks Cecil, I was concerned about spacing of the stub more than
anything else. I guesstimated this should be about a foot.
The bottom 1/4WL is a quarter-wave matching stub, either open
or shorted. If it is open, you have a Zepp antenna, and they
used to use open-wire transmission line for that. One foot
spacing may be a little much. Rule of thumb - 1% of a wavelength
would be about eight inches on 20m.
