Product Information
8750 Series, RF Loads are 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.
- Broadband water-cooled loads for long-term RF dissipation when heat must be efficiently transferred away from the area
- Small size may be carried easily, used in any position and installed anywhere there is a source of potable water
- 3-1/8" EIA Flanged and flangeless connectors allow termination of full 20 kW up to 900 MHz
- Requires flow rate of up to 9 gallons (34.2 liters) per minute
