    Diversity Combiners

    Troposcatter was the primary longhaul multi-channel communications network for the world-wide Defense Communications System. Sometimes called radio relay. BTW - The transmit string was baseband feeding 1 IF modulator (70MHz) feeding two up-converters (2.1 & 2.4 GHz, for example) feeding RF...
