[Elecraft] OT: Now Balun effectiveness

[Stuart Rohre]

Darrell,
I missed your main point which is true.  Re Read your post, and have to
agree strongly:  IN multiband use, the coax run becomes a loss mechanism as
the feedpoint values vary.  The choke balun does not lose much, but the
length of coax with its distributed L and C and SWR upon it certainly will.

For multiband doublets, (dipoles) a balanced ladder line feed, or open wire
line, (any parallel line) will have lower losses due to varying SWR over
bands, as it is higher impedance than common coaxes.
This is for the case of long runs of coax vs. parallel lines.

Certainly, parallel line is the way to go for home runs of 100 feet or more,
and even for lesser runs where convenient.
