8921, Oil-Cooled RF Load is self-contained high-power 50 ohm coaxial transmission line terminations requiring no outside power source or additional equipment. The units provide accurate, dependable, and practically non-reflective termination for testing and adjusting transmitters under non-radiating conditions. The loads consist essentially of a cylindrical film type resistor immersed in a dielectric coolant. The resistor, individually selected for its accuracy, is enclosed in a special tapered housing which provides a linear reduction in surge impedance directly proportional to the distance along the resistor. This produces the uniform, practically reflection-less line termination from dc to 1 GHz. Specifications Power Rating: 5000W Continuous Frequency Range: DC - 1 GHz VSWR: DC - 1 GHz, 1.10 to 1.00 (Measured using a N-Type Female Connector) Impedance: 50 Ohms Connector: LC Female Coolant: Oil-Cooled
