Abstract :
Several diversity techniques employed in uhf beyond-the-horizon systems are discussed. Field experience is evaluated in terms of equipment reliability, flexibility and performance. A nonswitching parallel combiner has become the standard military diversity circuit for uhf long-range receivers. The circuit is described and analyzed.
