Thanks! As it turned out, I have a RigExpert AA-600, and it was very easy
to use as a TDR. Much easier than the NanoVNA.
Somewhere I have a real TDR, a TEK 1502. But it's in storage and is so
buried I couldn't find it.
My concern about the site was that the cable and antenna (for an FM radio
station) that I needed to measure is on a tower with many other antennas on
it. Instructions for the AA-600 note that transmitted signals from nearby
antennas could affect the TDR measurements and even possibly damage the
instrument. I suppose this could hold true for the NanoVNA, too. There did
not appear to be any effects of other signals on the TDR measurement when I
made it.
