[Elecraft] OT: Now Balun effectiveness

[Stuart Rohre]

Mike,
The point of an all around or compromise, non resonant antenna like the
Cebik 44 foot doublet is NOT to feed it with coax, ever, for multiband use!
Those antennas need parallel line feed, only.

Coax was developed for feeding resonant antennas that operate over a
relatively narrow part of the bands.

Parallel line was found early in radio history to work with low losses on
long or short runs at high SWR.   In the earliest days, SWR at the rig was
not a problem.  Folks either tuned their feeders or adjusted the coupling of
the rig by variable links, link tuning caps, or later the wide range Pi Net.
Modern solid state rigs leave out the variable, antenna tuning Pi net,
essentially selling transceivers lacking what came standard on rigs of the
50's.   That is why a good tuner is essential to today's hamshacks.
