Bird 8770 - Water Cooled RF Termination (50 kW)
The Bird 8775/76 Termaline Load Resistor is designed as a compact, low-reflection, and non-radiating termination for RF transmission lines. Cooled by internal water flow, it generates almost no surface heat, making installation space minimal and convenient. The load can safely dissipate up to 50 kilowatts of continuous power when used in a 50 ohm coaxial transmission line system.
These loads are intended for use on CW, AM, FM, SSB, and TV modulation envelopes, and within certain limitations on radar or pulse modes. They feature a small size and may be carried easily, used in any position and installed anywhere there is a source of potable water.
A flow rate of up to 11 gallons (41.8 liters) per minute is required.
