Antenna wire is 20-ga stranded wire.
By November 18, 2003 I was ready to try my latest pedestrian mobile
setup. This marked the day when I was finally free of the big balloons
I was using to lift my long, vertical wires. Don't get me wrong. The balloons
served me well, and were the only way I would ever be able to use a
full-sized halfwave antenna while mobile.
The idea for using a coil-loaded, end-fed halfwave for pedestrian mobile
was, as far as I know, first used by Peter, GØDZB, as
chronicled in an HFpack
posting on Yahoo.com. He designed a physically short halfwave that incorporated
two loading coils just as in a shortened dipole, but he turned it
vertically and fed it at the bottom. Then the October, 2003 issue of
QST arrived with an article by Luiz, CT1EOJ, titled Designing a
(pgs. 28-32). It gave me all the information I needed
to recreate Peter's antenna. And since it was still electrically a
halfwave, I could use the same matching unit from my previous
How well does it work? Signal reports received seemed close to what I
would expect with a full-size antenna. Running five watts here in
Colorado I worked Howard, K7HI/mm, who was working as a crew member
aboard a container ship. He was 500 miles off the coast of Hawaii and
running only one watt! (That was all the power he was allowed to run on the ship at
the time.) Below is a picture he sent of his "ham shack."

|The only constant is change, so I went back to the
drawing board and redesigned the shortened Zepp for dual-band use with a 20-foot
fishing pole. I buy my poles from Cabelas.com. Very inexpensive. Here
is the continuing story.
