[TowerTalk] Mosley Antenna Question

[Roger (K8RI) on TT]

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.
