Re VNA: I use miniVNA Tiny but the DG8SAQ is supposed to work very well.
Re antenna:
before finsishing experiments, I wanted to optimize the design of the thick/thin antenna.
I used MMANA and get the following results:

If you have a few minutes, could you tell me the what the result is with 4NEC2?
As you can see on the wire definition, this starts with a ground plane using 4 x 69mm long 2mm diameter wires at an angle of 20 deg below horizon.
Then a vertical section of 65mm long 8mm diameter
Then a sequence of 3 times : 138 mm long .2mm diameter followed by 130 mm long 8 mm diameter
