Field Universal HF Antenna RV3DA


Antenna RV3DA at 40-m

Vertical Radiation Pattern



Horizon Radiation Pattern





Comments: Antenna radiates mainly radio waves with horizontal polarization. A good pattern in the vertical plane. Antenna has strong zenith radiation that allows to do local QSOs. “Eight- figure” pattern in horizontal plane, so, it demands to choose a proper direction before an installation of the antenna. Antenna is fine for DX and local QSOs. Antenna has Z= 116+ j263-Ohms at 3800-kHz. Almost any ATU does good matching for such load.
