One other thing, I see, is that End Fed Dipoles
have a extremely high impedence, and hence a very
HIGH VOLTAGE (altho at little current), unlike
center-fed dipoles. Might make insulation
problematic to prevent arcing . Can generate
hundreds (if not Thousands) of volts, at the feed
point! Jim NN7K

Hi Chuck,

The slur may attend the illusion that just the antenna is being
matched and the operator cries foul about transmission line common
mode currents.

However, if those currents go unnoticed; then end fed antennas are
marvelous and have this undeserved bad reputation. On the other hand,
if those currents are noticed and fixed, the antenna probably doesn't
work any better; but after all that effort "it damned well should and
no one is going to convince me otherwise."

Then you have to have a pretty good tuner..
Along with whatever losses it provides..
I avoid tuners if at possible. None of my
everyday antennas use one.
I have a 989c, but I mainly use the wattmeter,
and switch..
The tuner itself sees little use. Probably has
spiders inside.. :/
