It's my opinion that there has been virtually nothing
"new" related to antennas since the 1930's. Only
the names have been changed, as the high number
of recent posters have shown.
Some even have reached "cult" status. I have a small
history of giving antenna seminars at hamfests, and
usually start a talk with "How many of you are using
G5RV's"? Usually, a large number of hands go up.
I make the observation that there seems to be a high
level of interest in 20M. After a pregnant pause for
the puzzled looks, I then point out that the G5RV was
designed as a 20M -ONLY- antenna. I have the original
Varney article from the RSGB where this is plainly stated.
I have no idea where the transition to an "all band"
antenna came from.
I then ask why go to the trouble to build dipole fed
with a "magic" length of open wire that is then
connected to a "magic" length of coax without any
form of impedance transformation? The "required"
length of coax is (usually) much longer than needed
and ends up coiled up somewhere, as in the case of
a local friend who coiled his excess at his feet. Why
not run the open wire directly to a tuner ... which
-WILL- be needed anyway ... via a balun? Viola!
One has a classic, easily used "all band" dipole.
The "Carolina Windom"? The Windom has been with
us since the 30"s, and the "Carolina" is a marketing
ploy.
A recent poster gave a correct description of the "why"
of an end-fed zepp
73!
