Its design is very strong and robust resistant to strong winds (110 kmh). The material used for the construction of. This glass fiber rods, aluminum, stainless steel and galvanized steel. Sealed box resistant to rain and UV rays. In the forests is installed balun.
The antenna works well on DX and as a QRP station. It is pre-tuned to different bands at the height of 4 metres above the ground.To widen the bands 6 and 10 m is useful box ATU. Radiation antenna is omni-directionally so you do not need a rotator. It is a half-wave dipoles 14,18,21,24,28,50,70 MHz.
In horizontal polarization resistant to electrical interference and static. Large system efficiency to 95%. The antenna is pre-tuned a little lower to cover FT8 and low SSB.
If you do not need a 10m band when it is not in use, you can tune it to CB band (27 555). See the illustrative photo of the antenna's operating width on each band.
