5 kW, Oil-Cooled Terminations Termaline® Series RF Coaxial Terminations The 8920 Series TERMALINE® Load Resistors are 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 nonreflective termination for testing and adjusting transmitters under nonradiating 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 reflectionless line termination from dc to 1 GHz. · An 8890-008 over-temperature interlock safety switch is optional · This series has includes Models 8922D, 8926D and 8927D for Digital BroadcastVSWR = 1.056 max., 470-860 MHz 8820 Series, Terminations Model Connector Diminsions, L x W x H Weight 8921 QC, LC (F) 30-27/32" x 9-1/2" x 25-13/16" (783 x 241 x 656 mm) 119 lbs.
