The 4170 makes this a lot easier as you can measure the feedline actual
parameters as well as calibrate out their effects.

This is a dumb question on my part, but what you are saying is that the
mitigating effects that the cable has on the VSWR, making it look better
in general, can not only be calculated and "calibrated out", but that
the actual SWR of your antenna at the feedpoint is then given?

As you get closer to 1.1:1 at the actual antenna, would accuracy then
suffer? If feedline loss can bring an antenna that is not near that to a
level approaching that, wouldn't it mean that teh calibration is
somewhere in the noise?

Like I say, this could be a really stoopid question.
