according to N0AX there "wasn't enough time and energy" to put a choke or balun
on even one Mosley antenna when feedline radiation would be or was suspect in
causing the performance to be less than that of a dipole that DID have a
feedline choke installed. As VE7RF would say...WTF?

A few observations: Wasn't the point of the K7LXC/N0AX report to provide a
solid comparison of what the average amateur could expect to get for his/her
money? How many "average" hams are going to look past Mosley's
baffle-them-with-bullcrap of not needing a balun, especially if they've been
schooled in the K7LXC Prime Directive?
As well, if you have to mess with a new antenna out of the box to get it to
work right, is it really a good design? Clearly, it appears they can benefit
from a balun.
