Vertical Radiation Pattern



Horizon Radiation Pattern





Comments: Antenna has strong vertical radiation. A good pattern in the vertical plane. Antenna has egg shape pattern in horizontal plane, so, it demands to choose a proper direction before an installation of the antenna. Antenna provides DX QSOs. Antenna has Z= 121+ j90-Ohms at 18120-kHz. Any ATU does good matching for such load.
