I tend to make my SWR readings right at the antenna, whenever
possible. That length of coax to the xceiver will only make it look
better in most cases.

Mike,

With the 4170 I can calibrate the instrument to compensate for the
feeder impedance. After calibration, the indicated impedance at the TX
end of the feeder is actually the antenna feedpoint impedance. This
makes life a *lot* easier.

Oaky, well good enough. My vertical uses a stub on the feedline, so I
have to be out there anyhow.with a connector in the line. Seems like 6
of one, half dozen of the other situation.

Agreed. But I guess your antenna feedpoint is more-or-less at ground
level. That's a little different from peering through binoculars at an
MFJ suspended at the feedpoint 50ft above ground .... grin
