Don't know when Mosley was introduced, but I installed the array between
2000 and 2002 with all LMR-400, which IIRC was fairly new. I "think"
the Mosley design had been around for quite a while although I've never
owned one.
When I installed my first 3L tribander in late 61 or early 62 I think
all tribanders used traps. I don't remember the make or model, but it
had molded blue traps. They "appeared" to be fiberglass, but appeared
and actual construction may be different. The color and design sound
like the early Hy-Gain. Soldid, molded, must have been pretty poor at
radiating heat from losses.
I don't remember my first tri-bander after moving to Breckenridge MI
either, but shortly there after went to the monobanders. I originally
had a 204BA, before the KLMs
It seems like maybe Mosley came out with a trap vertical early on?
60s,70s, or 80s?
It also seems as many of the reports, good or bad were anecdotal, but
many, like Jim's are rather concrete.
By their very nature, most reports were anecdotal and individually a bit
unreliable, but large numbers would indicate a trend. As I said before,
there are many, many ways a station with good equipment can be a poor
performer. Many of the great claims for performance came from "in spite
of the design, not because of it"
Many of the manufacturers back then relied on simple designs as
computers, let alone today's sophisticated modeling programs were not
available.
After looking at what works today, I'm amazed that much of the old
"stuff" even appeared to come near the commonly inflated performance
claims. OTOH we mostly ran a fraction of today's common power levels
with little processing. There were the proverbial California Kilowatts,
but nothing near the numbers today
Relatively speaking, when inflation (value of the dollar) is taken into
account, fairly simple amps cost as much or more than the top end,
computer controlled, auto tuning amps of today and typically ran power
levels comparable to the over rated starter amps of today. Not many
coul afford amps capable of burning up traps. That and the FCC was a lot
more enforcement conscious of power levels.

Could it be that LMR400 wasn't available or too expensive way back when the
Mosley manual was written?

I had a similar setup (except mine was a PRO-57A) and had

Without specific data I can only conclude that some folks have
had some bad experiences therefore all their antennas are "bad".
Not from where I stand, and the proof is in the pudding, as they
say.
