After numerous requests, Balun Designs is pleased to offer a specialized 1:1 balun optimized for 6 meters.   The material for this core is optimized for 50-54 MHz and provides exceptional choking impedance at these frequencies.  An...

This is a departure from the normal 1:1 isolation/choke balun and utilizes a bifilar pair designed to handle the high voltages created by multiband antennas such as doublets and multiband loops  The 1151 is ideal for moderate power operations, is...

22/25 ohms unbalanced to 50 Ohms unbalanced Unlike Baluns, Unun's (unbalanced to unbalanced) provide impedance transformation for antennas that are naturally unbalanced because of their design configuration. Even though the unun's appear small...

This is a balun originally designed by Guanella and subsequently improved by Dr. Jerry Sevick (W2FMI). By utilizing Thermaleze wire inserted in teflon tubes, Dr. Sevick was able to substantially increase the breakdown voltage between both...

This is the single core version of our popular 4:1 unun model 4134 designed for use with wire verticals, random length long wires and multiband verticals. Wound on a single core for reduced power applications, this unun delivers efficient broadband...

Balun Designs now offers an excellent reduced power version of our popular model 49131.  Built with the same craftsmanship as all our other units, this new model will allow you to either replace your current matching unit or construct a new medium...
