These VSWR measurements were taken in the open field at a height of 10 meters horizontally.
We use 4.5 meter of coax to a line isolator.
From the line isolator to the analyzer we used 10 meters of coax Ecoflex 10, with very little loss.
Coax loss Ecoflex 10 :
5 MHz 0,8 dB/100m
10 MHz 1,2 dB/100m
50 MHz 2,8 dB/100m
The antenna network box was positioned 6 meter above the ground.
The length of the antenna wire to the matching network is 23 meters and connected to an 6 meter mast.
The antenna was not grounded.
