The tm-1/tl-2 short haul microwave systems

This paper describes the design and discusses the performance of the TM-1 and TL-2 radio relay systems designed for short haul service in the 5925 to 6425 megacycle and the 10,700 to 11,700 megacycle common carrier bands, respectively. Used as a crossband diversity pair, they provide a highly reliable broadband message channel for up to 600 circuits and require little maintenance and relatively low power. These systems are also used to transmit television.
