These VSWR measurements were taken in the open field at a height of 10 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 10 meter above the ground.
The length of the antenna wire to the matching network is 40 meters and connected to an 12 meter mast.

The antenna was not grounded.

Used VSWR meter : RigExpert AA-600

Impressive performance in CW with 1kW during the contest as running station. No core saturation, no increase in SWR. I strongly recommend!
