A full line of medium power terminations which use special load elements for the best electrical performance. The waveguide is made of OFHC copper and brass fins are used for heat sinking. These units are used for medium power applications to terminate waveguide transmission lines with a very good VSWR characteristic. VSWR is less than 1.05 maximum over the full waveguide bandwidth. All tolerances are + or – .020. Finish is flat black unless otherwise specified.
