Steve:
I am not sure I understand how it becomes the responsibility of the antenna
manufacturer to solve system problems. In two postings we have seen comments
to the effect that Force-12 was insufficiently response to their request for
system assistance. I thought that Force-12 sold antennas (and perhaps
customer support for those antennas). I did not realize that they were in
the antenna-feedline-tuner-amplifier-transceiver system consulting business.
I note that in your e-mail response you also stated this concept. ( That the
system is the responsibility of the system integrator not any particular
manufacturer of a system sub-assembly). You said, "My last two "antenna"
problems for customers were both in the shack - one was a bad piece of coax
and the other was a
flakey coax switch. " In these examples you are providing the systems
analysis service and not looking to the manufacturers of the components to
identify and resolve the system problem.

This is a common problem. My last two "antenna" problems for customers
were both in the shack - one was a bad piece of coax and the other was a
flakey coax switch.
The best thing to do when confronted with a similar problem is to plug
the antenna feedline DIRECTLY into the rig and see what you've got. If
that's
fine, then start working backwards with the other stuff in the feedline. If
the SWR is still bad, then you know the problem is either the feedline,
balun
or antenna.
Sometimes I'll get a different reading at the end of the coax from my
MFJ259 than the rig in the shack. Go with what the rig sees since that's the
only criteria that matters.
As far as Natan, he's W6XR/2 and answers lots of Force 12 product and
technical questions. Marianne (Mary) is Tom's dad's wife and she is the
office
manager. Apparently Tom is out of the office until August 10. Anyone that
has
a problem or question until then is even more SOL than usual.
