I can now verify that the FA-VA5 does just fine on my 160 meter inverted-L.
As an aside, we've had some rain here in Tucson lately and I've observed a
decrease in the feedpoint Z of about 5 ohm due to increased ground
conductivity. Welcome, but I know it's temporary.

I can vouch for the AA-55 Zoom, although it is not without flaws. I live 5.9
miles from a 50KW BC station on 1550 kHz. On my 160-meter inverted-L they are
70 dB over S9 on a calibrated K3, that's 70 dB above -73 dBm or -3dBm. As long
as I don't sweep through that frequency, the analyzer is unfazed. As an
aside, I have yet to find a low cost SDR that will stand up to this. I had to
return a RSP2 Pro that even with BC band filtering folded up like a cheap
suitcase.
My N2PK VNA works fine as does the DG8SAQ VNWA. I just last night finished
building a DG5MK designed FA-VA5, which I suspect will do okay. It will run
using the VNWA software too. Good thing, since so far, the standalone
interface is wanting, but that could be my failing. (It's really tough to run
an instrument this powerful with just three push buttons)
Note that all of these are vector analyzers.
