Adjusting SWR:
Once positioned the antenna with your measurements,
you may need some fine-tuning to get the SWR desired
.
Shifting
the curve piece inward or outward several millimeters,
is the way to go.
Looking to the center frequency is 50,150 MHz
in the lower SWR. The best option is to adjust with analyzer or with the help of a swr meter and antenna 1 or 2 meters above
the ground while it is sufficient to have achieved in the setting, give us the same results being any other height on the tower or
mast.

Coax cable feeding:
After several trials, we see that the balun aluminum makes it worse job than a coaxial choke. For this, we recommend 5 turns
of 8 cm and thus the RF return will be minimal or absent.
The drawing advises you to mount the coil below the boom, this does not cause interaction with the elements.
