It's the classic marketing axiom: tell people what they WANT to hear, not
what they need to hear and, often, certainly not the truth!
A lot of marketing, even in a relatively technical field such as ham radio,
plays to a certain level of ignorance in the average audience member.
Tell someone that all baluns are lossy and that you've "designed" a "feed
system" that doesn't require a balun and you'll prove PT Barnum correct,
even if that "feed system" is nothing more than coax directly feeding a
split driven element...
Tell someone the FL-2100B they've used for 30 years uses "potentially
DANGEROUS horizontal mounting" of the tubes and you might frighten them into
buying your amp.
It's the same kind of spin that got people so excited about that magically
broadband dipole that was nothing more that two wires attached to a dummy
load inside the centre insulator...
That being said, I have a Mosley sitting somewhere under the snow. I might
even put it into service, but I'll do so knowing exactly what my $50
bought...
