The ACA-30-xxR Series with Passive Return Path are hybrid indoor broadband distribution amplifiers designed to be used in RF distribution systems such as those for apartment complexes, hospitals, schools, prisons, and hotels. Ideal for RF distribution systems whose input signal source is a “cable drop”, the output of an MATV headend or a small CATV headend. Three models are available with bandpass ranges of 47-550 MHz, 47-750 MHz, and 47-860 MHz. Each model is powered by an external AC/DC adapter.
