UHF 6700D SERIES DUMMY LOADS

Altronic Research 6700D Series are top quality, high powered forced air loads for UHF. Since 1986 we’ve used our own proprietary film resistors in our 6700 Series air loads to provide our customers with superior products with unmatched performance. Now, with our advanced tuning techniques, we offer an operating range from 470 to 810 MHz with stable and low VSWR. In keeping with our commitment to provide our customers with top quality products and services, the Altronic 6700D Series sets the standard for UHF TV reliability, quiet operation and field serviceability. When choosing an air load for UHF, choose an Altronic air cooled RF coaxial load resistor. Consult factory for available models, power ratings, and warranty information.
