See the "Super J" in the "ARRL Antenna Book", page 16-25 in my 19th
edition. That is more or less how it is made. The two 1/2-waves,
in-phase, are end-driven with phase inversion provided by a
short-circuited 1/4-wave stub between them.


I just picked up the ARRL book, it's a daunting tome... but interesting
reading.

At frequencies higher than 2-meters, this would work for more than (2)
1/2-wave sections. The practical limitation is mechanical.

Makes sense, thanks.

One of these days, hopefully in the near future, I'll get off my ass and
take the ham test. Time.. always about time.
