1 kW, Oil-Cooled Terminations
The 8251 Series are portable, self-contained general purpose 50 ohm coaxial transmission line terminations requiring no outside power source
or additional equipment. The loads are Oil-assisted convection cooling for safe, continuous operation up to 1000W full rated power. They provide 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.
