Oil-Cooled
1.5 kW RF Load Series

The 8860 Series RF Load is a high-power, self-contained termination for continuous-duty testing of RF transmitters and systems up to 1500 watts. With oil-assisted convection cooling, it provides low-reflection, stable performance across a wide frequency range—no external power or cooling required.

A precision-tapered resistor, immersed in dielectric coolant, maintains consistent 50-ohm impedance and efficient heat dissipation, making it ideal for high-power, non-radiating test applications in lab and service environments.
