[Antennas] Tower Installation

[Alex Eban]

I usually don't get involved, but this is unfair!
Dipoles ARE balanced antennas and a such benefit from a balanced feed. As
such, employing a balanced lie of any kind is beneficial, no matter what
kind of line it is. What you DO get is much lower losses in the line when
the SWR is high. Losses in the line are proportional to the line voltage
squared!  Doublets have been known to work efficiently even when the antenna
is way off resonance. 
The coax myth came about when coax became available cheap after the war and
SWR bridges became commonplace. We all go used to trading bandwidth-- stick
around some design frequency, trembling from fear the SWR needle will
budge-- and forgot that an open line can run at a 20:1 VSWR with no problem.
If the tuner copes, everything's fine. And don't forget that a lot of radios
have a built in autotuner anyway!
Soooo, where the lie?!?

That's a bold face lie!

I'll run the race and I will never be the same again.

Don't waste your time using coax on a dipole; it's a lie perpetrated by the
ARRL.
