8730 Series, RF Loads are designed as compact, low VSWR and non-radiating terminations for high-power transmitter/transmission line systems. The units generate 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 load 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
Requires flow rate of 4 gallons (15.2 liters) per minute
