5 kW, Direct Water-Cooled RF Termination
8720, RF Load is designed as a compact, low VSWR and non-radiating termination for high-power transmitter/transmission line systems. It generates almost no ambient heat, making installation space minimal and convenient, in any position. The RF power is converted to heat in the hollow resistive film load resistor and directly absorbed by the water flowing through it.
