This is one of several new UNUN's being added to the Balun Designs line of quality products. This ratio is primarily designed to match unbalanced 50 ohm loads to 75 ohm coax feedlines.
Unlike Baluns, Unun's (unbalanced to unbalanced) provide impedance transformation for antennas that are naturally unbalanced because of their construction configuration. Even though the unun's appear small is size, they are able to handle very high power (3kW continuous - matched condition) because of their excellent efficiency.
75 to 50 ohms
Many other unun ratios are available by contacting us via the methods shown in the Contact Us tab.
Special mix toroid with low permeability. Toroid is also coated with epoxy paint for extra durablity.
Design has excellent broadband frequency response and is very efficient (99%).
Windings of trifilar 14 gauge Thermaleze wire.
Insertion loss is < 0.1db. 1 to 30MHz usable frequency range.
SO-239 connectors are silver plated with teflon insulation and gold center conductor.
All hardware is Stainless Steel.
Alternate connectors plus mounting options are available in the Accessories section.
