CATV 1 x 4 Splitter / Drop Amplifier This cable drop amplifier sends CATV signals to up to four television sets with an internal 15dB signal amplifier to compensate for losses caused by the split and additional cable length. It also provides a passive return path, ensuring compatibility with current digital and interactive and broadband cable systems. While designed for CATV use, this device is perfectly suitable for use with standard TV and FM antennas. The housing and 'F' ports are all sealed for permanent installation outdoors.
