Featured ProductsRFS ClearFill Plenum-Rated Coaxial Cable for In-Building Applications RFS delivers a cost-effective, in-building solution with its ClearFill plenum-rated air-dielectric coaxial cable, CATVP-rated, with low flame-spread and low-smoke characteristics, it is ideal for use within the building plenum defined as the “environmental air handling space.” This permits use of the cable as part of an in-building Distributed Antenna System (DAS). Plenum-rated cables, tested in accordance with the National Fire Protection Agency (NFPA) testing method 262, have the most stringent flame retardant and smoke-suppressant characteristics. Due to their low attenuation, outstanding heat transfer properties, and temperature-stabilized dielectric materials, RFS plenum-rated cables provide a safe, long-term operating life at high-transmit power levels.

Power TMA's While Providing Basic Performance Monitoring
RFS PDU1912 is a power distribution unit intended for use with RFS' Tower Mount Amplifiers. It provides direct current through the bias-T to power six units of dual-band or single band TMA's. Green LED's near each connector indicate the functionality of the TMA's. If a fault occurs in the TMA, the LED will either change to red or yellow depending on the fault condition as indicated in the specification. The PDU1912 can be mounted in a standard 19" rack and is one rack unit high. All DC connectors come with mating connectors and the unit includes individual reset switches for each port PDU1912-0
