These VSWR measurements were taken in the open field at a height of 5 meters horizontally.

We use 2.1 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.
