Review Summary For : Bird model: 8251 1KW DUMMY LOAD
Reviews: 1MSRP:
1000 Watt, Oil-Cooled RF Termination 8251 Series, RF Loads are portable, self-contained general purpose 50 ohm coaxial transmission line RF terminations requiring no outside power source or additional equipment. The loads are Oil-assisted convection cooling for safe, continuous operation up to 1000W full rated power. They provide accurate, dependable, and practically non-reflective termination for testing and adjusting transmitters under non-radiating conditions. The load consists essentially of a cylindrical film type resistor immersed in a dielectric coolant. The resistor, individually selected for its accuracy, is enclosed in a special tapered housing which provides a linear reduction in surge impedance directly proportional to the distance along the resistor. Note: This series includes Models 8251D and 8251D7-16 for Digital Broadcast (VSWR = 1.065 max., 470-860 MHz)

Quality dummy load and wouldn’t bother with any other. Time Owned: 3 to 6 months.
What more does one have to say about Bird products?

They look like robust military quality testing equipment that could last forever and they can. Dumping 1Kw into mine numerous times testing equipment and doesn’t even get hot. Quickly little by little dumping a little more to full legal limit briefly and still zero problems. They say if you place a couple box fans underneath to vent and cool the fins you’ll easily be able to dump 1.5kw with no issues.

Either way, great product and deserves to be mentioned.
