Diversity Reception

November 11th Fact-of-the-Day

High-frequency signals from a distant transmitter fade at different times when received by identical antennas spaced a few wavelengths apart, by co-located vertically and horizontally polarized antennas, or when received on the same antenna if transmitted on different frequencies. Diversity reception systems take advantage of this by using two or more receivers connected separately to different spaced antennas, to vertically and horizontally polarized antennas, or tuned to different frequencies and then using only the output of the receiver receiving the strongest signal at any instant in time to reduce received signal fading. ©2004 Martek International All rights reserved.
