Effortless Cooling for Demanding RF.

Water-Cooled
40 kW RF Load

The 8765 is a high-power, low-VSWR RF load designed for continuous-duty operation in broadcast and industrial systems up to 900 MHz. Its streamlined form factor and direct water-cooling architecture convert RF energy into heat through a hollow resistive element—reducing ambient temperature rise and ensuring reliable performance over long durations.

Equipped with a 3-1/8" EIA flanged connector and requiring 10 GPM of cooling flow, the 8765 is built for high-capacity environments where thermal stability and RF precision are critical.
