Radiation Patterns of Antennas at the U.S. Coast Guard Radio Station, San Francisco, California.

Abstract

Electromagnetic radiation pattern shapes were measured for four transmitting and five receiving antennas located at the U.S. Coast Guard Radio Station near San Francisco. All antennas were broadband, operating over a portion of the high frequency band with vertical or horizontal polarization and in one case circular polarization. Contour pattern plots were determined for a number of frequencies over the designed operating frequency range of the antenna. Elevation pattern plots were constructed for a selected number of antennas. A reference or control whip antenna was used to verify measurement results. Information is presented about the relative gain of these antennas.
