YES, absolutely. That mode plus the stub length calculations are extremely useful. The beauty of these self contained analyzers is how easy they are to use in the field. My only wish, though minor, would be the ability to store multiple OSL calibrations like one can do with the professional (expensive) VNA's (Anritsu, etc.).

RigExpert has *All Parameters Mode* when it will display the R, X and the
Resonant Frequency. This is the most useful screen for tuning an antenna.
You can move up and down the frequency to see R and X at different points.
The same screen shows SWR calculated for the impedance set in the settings
of the Rig Expert. You can see it to 25, 50, 75 and 100 Ohm

I have never used a RigExpert analyzer but according to the manual (page 8)
there is a data screen that will display the various parameters. If you're
trying to attach only an SWR chart, it's pointless.  Does the Hy-Gain
vertical come with any type of matching device or does the antenna just
rely
on high ground losses for low SWR?

Hi Al and all,
I recently bought a RigExpert AA-230 ZOOM and that's what I measured the
SWR
with.  I haven't had a chance to figure out, or use the other features yet
but it's high on my To-Do list. Here's a copy of the attachment that didn't
make it on TowerTalk. I'm not sure if I can send attachments via TowerTalk.
Thank you for your replies.  I really appreciate it!
