Howard,
I used the SMA to SMA jumper cables which came with the Nano VNA and
calibrated using the open, short and load connectors (
). Then I used an SMA to SO239 adapter on the
jumper cables as my antennas have PL259 termination and it worked well.
Somehow it did not work well when I used PL259 open, short and load for
calibration.
If your antennas have SMA termination, then there is no need to use the
adapter. I did not use any software other than the built-in software in the
Nano VNA.

Hey guys
just got a nano VNA. it is a "seesii, nano VNA-H.
I need some help in setting it up to see the SWR on some antennas. I have
gone through the various manuals and the one that came with it, and I am
very confused.
Basically what I am looking to do is (to me ) very simple. Input a start
frequency, lets say 144 MHz. A stop frequency, say 152 MHz. The see the
lowest SWR point as an inverted bell curve.
Anyone have any ideas how to do this? Also, I cannot seem to find the
correct software for the device. I know my cable is good (as I can get data
off my cell phone with it) but i cant the nano VNA to be recognized.
Please help.
Howard
