This is a departure from the normal 1:1 isolation/choke balun wound with coax. The bifilar pair used to wind the balun is designed to handle the high voltages typically found on multiband antennas...

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...

This balun is an excellent step up from the model 4113, is not sensitive to high power reflected RF like the model 4115 and is the best choice when running high power digital modes such as FT8.
