Comments:
Antenna has strong horizon radiation. For the horizon
radiation antenna has a not bad pattern in the vertical plane,
and "eight- figure" pattern dropped to lobes in the
horizon plane. Antenna can provide DX QSOs at the horizon radiation.
Antenna has impedance 396+j227-Ohms at 28600-kHz. Not all ATUs
do good matching for such load. |
