The issue is that nobody wants to hear or find out that what they bought
was not as good as another product or that product X which is less might
be better.
If you are happy with your Mosley great. Then why get your panties in a
bunch.
Whatever you have now is probably better than what you had before, right?
I worked a pile of DX with a TH7DXX and a TA33JR. I have worked a heck
of a lot more with my SteppIR's. Is a non trapped antenna better than a
trapped one. You can do the research on that. I am pretty sure the
TA33 jr ended up in V47 land and it made a pile of contacts. It was
simple to build setup and use. Did the Monobanders we brought down
later work better....Yep. Do I have any regrets, nope. Most multiband
antennas require you to give up something to have multiple bands.
I got into the same conversation on Facebook with people about the
Baofung or whatever it is dual band HT that you can buy for $35.00 or
less. People that spent way more another brand radio, went out of their
way to bash the $35.00 radio and they never even owned one.
Operator skill plays a big part of working DX. You can have the biggest
and best but if you don't know when and where to call you probably are
not getting in the log.

The point many Mosley supporters don't seem to understand is that from the
results of one antenna, you cannot derive any knowledge about whether it is
outperforming another yagi of comparable cost or dimensions.
A person who puts up a TH7 and uses it exclusively for ten years can proclaim
he was happy with the performance, but has no basis for proclaiming it would
have outperformed, say, a Skyhawk, JK Tribander, X7 or even a Pro57.
Someone who took down a TA 33 and replaced it with an A4s and notices an
improvement DOES have a basis for regretting buying the TA33, however.
An engineer and a tower expert who create a scientific plan for comparing
antennas and execute that plan do have a basis for saying that one brand of
antennas was inferior to competing, comparable models, as well.
The plural of anecdote is not data. Only by sound comparison can one say for
certain that spending $1,500 with Mosley is better than spending $1,500 with DX
Engineering or Hy-Gain or JK.

Indeed everything works. That supposition does not rule out some things working
far better then others with the proof being in the empirical evidence of
experience by making contacts. I don't need an antenna range or a model to
tell me the Mosley tri-bander that's going up in the spring is going to be
light years better then the MFJ loop tuner I have sitting on a chair in my
spare bedroom. As for measuring performance... I have yet to hear an Asiatic
station, much less work one. I expect that will change with the advent of my
yagi going up and when the QSL cards start rolling in from JA that's all the
measurement I need. 73,

You do not need an efficient antenna to work DX and without a way to
compare it to other antennas you have no way to measure its performance.

K7LXC will not "talk his book" but I will say that multiple unbiased
antenna range tests - including those reported in the K7LXC/N0AX
"Tribander Test Reports" - have shown that the Mosley antennas perform
more poorly than any other manufacturer's multiband yagis of similar
boom lengths.
It's a bit of a stretch to call it a "book" -- it's a well-written,
well-documented engineering report on the well-planned and well-executed
antenna measurements that Steve and Ward did something like 12-15 years
ago. This report, another on companion tests on HF verticals, and N6BT's
"Array of Light" book are all available from Steve's Champion Radio
website, and all are worth far more than what you pay for them.
The N6BT book is really about antenna design, discusses the designs of his
Force 12 antennas, and includes designs for a nice variety of HF antennas.
The only thing it lacks is an editor -- several chapters are redundant.
One of the chapters debunks the inflated gain claims of antenna
manufacturers, showing that the advertised gain numbers for their
tri-banders were 3-6 dB greater than the maximum possible gain for a
monoband Yagi of comparable size.
