The NBS704-C48 is a multi-band amplifier designed to boost signals from different terrestrial reception antennas, ideal for medium-sized installations.

It features a switching power supply that powers the preamplifiers through the UHF inputs and controls signal level through intermediate stage attenuators. The F connectors provide a secure connection for each input and output, while it includes a grounding terminal and the ability to be mounted on a wall for indoor placement.
