ATX's exclusive, patented tiered design of drop amplifiers are equipped with low-intermod circuitry and GaAs technology. The 1 and 2 port tiered models allow access to all connectors on one side of the unit (compact size for use with subscriber lock box) thereby enabling users to more easily access the RF connection ports, especially when the unit is installed in a subscriber lock box. Exceptional RF performance, surge protection (CAT B3 Combination Wave versions), visible LED for power verification, and a waterproof SCTE compliant outdoor housing round out the features.
