* Simple but rugged design minimizes maintenance requirements.
The Model 8921 TERMALINE Load Resistor is a self-contained high-power 50 ohm coaxial transmission line termination requiring no outside power source or additional equipment. It provides accurate, dependable, and practically nonreflective termination for testing and adjusting transmitters under nonradiating conditions. The load consists 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.
Ambient Temperature Range: -40 C to +45 C
Frequency Range and VSWR: DC to 1 GHz at 1.1 max.
Load Coolant: 6 2/3 gal. (25.3 liters) silicone oil
