ABSTRACT:
A repeater system includes a plurality of repeaters, a low level combining circuit, and a tower unit for attachment to an antenna tower. The tower unit includes a linear amplifier, duplexer, filter, and low noise amplifier. The repeaters do not have final amplifiers. Instead, the low level combining circuit couples the signals from each repeater to the tower unit. The output from the linear amplifier in the tower unit is coupled to an antenna over a relatively short cable.
