Got one for you gurus and mavens.

I'm runnning an unbalanced roller T tuner through a balun to ladderline.

I want to set up a chart of mid band tune points so I can QSY reasonably
quickly and with minimum fuss of knob twiddling.

I have a small antenna analyzer. Can I just put this on the rig side of the
tuner, and use it to find matchpoints? Would I set it on 50 ohms, and then
adjust the tuner controls until I get that?

That will work fairly well, as long as there isn't enough
strong-signal energy hitting the antenna to confuse the antenna
analyzer and cause false readings. For example, trying to use an MFJ
analyzer to tune up an 80-meter antenna in an urban area can (I
understand) be quite an exercise in frustration, because the strong
signals from local AM broadcast stations are enough to cause the
analyzer to mis-indicate the antenna system's SWR.

I'd say, go right ahead and make these measurements... but make 'em in
pencil, and plan on verifying them using your transmitter (at low
power) and an in-line forward/reflected-power SWR meter.
