GRANGER ASSOCIATES POINT-TO-POINT LOG PERIODIC ANTENNA SYSTEM

Abstract

The electrical characteristics of log periodic high frequency antennas installed for the Federal Aviation Agency Research and Development Service at Barnegat, New Jersey, and an Juan, Puerto Rico, sites are described. The antenna at Barnegat is a horizontally polarized receiving antenna modified to meet special requirements of the FAA. The antenna at San Juan is a standard vertically polarized Model 726-2.5/30-T transmitting antenna. The results of model radiation pattern measurements, impedance measurements, ground reflection calculations, and cable attenuation calculations are given for the Barnegat antenna. The general radiation pattern, results of impedance measurements, and cable attenuation calculations are given for the San Juan antenna. Calculated values of installed gain are derived for each antenna.
