Abstract :
Signal fading at 836 Mc on a mobile radio transmission path using directional antennas on the mobile unit was investigated and compared with that from an omnidirectional antenna. A marked reduction in fading rate was observed with the directional antenna. Increasing the directivity decreased the fading rate. The average propagation loss was also measured for the various antennas over the two-mile signal path.
