AIR COOLED DUMMY LOADS

6700 SERIES COAXIAL LOADS
These air dielectric coaxial loads deliver the same high performance of the 6700 Series in a smaller package. The 6400 Series was designed to operate using static or forced air while exhibiting stable RF characteristics. The small, compact oil free design is a welcome advantage in a busy transmitter area. Applications run from mounting on top of the transmitter to placing them inside the cabinet. Model 640105 is an excellent load for VHF transmitters with separate inputs for the aural and visual ports.
  • Silver contacts on special film resistors and clips eliminate resistor failure due to contact resistance and make possible the superior RF performance.
  • Easy air ducting, extremely quiet, standby operation, interlock, alarm output, and easy to find replacement components.
  • The 6700 Series has set new industry standards for all areas of performance, reliability, and value.
