80 Series loads are portable, general purpose coaxial transmission line terminations. They are self-contained units, liquid free and air cooled, requiring no outside power source or additional equipment. They provide accurate, dependable, and practically non-reflective terminations for testing and adjusting RF transmitters under non-radiating conditions.

They can absorb their maximum rated RF power continusously and dissipate it harmlessly as heat over their entire frequency range. Becuase they are dry, they are attitude insensitive and can be used in any position.

These loads by design are used for portable operation. However, they may be used in fixed installations. They are light enough to be attached directly to the mating RF connecotr or another device such as a Bird Thruline Wattmeter or simply set on the workbench.

Applications:

• As a Substitute Antenna:
  • Tuning RF transmitters under non-radiating conditions
  • Routine test and adjustments
• Substitute for any circuit loading element
• To measure, with a suitable indicating device, the power output of any coaxially transmitted RF signal within their rating
