Comments:
Antenna has both, a strong vertical and strong horizon radiation.
For the vertical radiation antenna has a good pattern in the vertical
plane, and almost circular pattern in the horizon plane. Pattern
for horizon radiation is not so good as to vertical polarization.
Antenna can provide DX QSOs at vertical and horizon radiation.
Antenna has impedance 1711+j466-Ohms at 18220-kHz. Not all ATUs
do good matching for such load. |
