[TowerTalk] Ladderline - what are the facts??/

[Rob Atkinson]

It's probably not a big deal if an antenna is slightly unbalanced and
there is some resulting common mode current on parallel wire line, if
the circuit transforming the parallel line Z to 50 ohms unbalanced is
a balanced network and there is an adequate  common mode choke on the
50 ohm unbalanced line at the tuner.  The parallel line will radiate
of course but so what.  The radiation is probably represents a
negligible percentage of the total power put on the line.  Anyone
uncomfortable with these assumptions can get a parallel wire RF amp
meter from MFJ and check their line to be sure, and try making
adjustments if the line turns out to be extremely unbalanced.
