Low-profile, water-cooled RF solution

Water-Cooled
5 kW RF Load

The 8720 RF Load is a high-power, direct water-cooled termination designed for compact installations and extended use. RF energy is dissipated within a hollow resistive film element, with internal water flow efficiently removing heat—maintaining low ambient temperatures even during sustained 5 kW operation.

Its broadband, low-VSWR design makes it ideal for transmitter testing, load substitution, and non-radiating alignment in environments where space, cooling efficiency, and system flexibility are critical.
