Doublets

This low power balun is one of our newest offerings and provides over 30db of suppression across the full HF spectrum of frequencies. Our design provides high levels of feedline isolation, RF choking...

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

This is a departure from the normal 1:1 isolation/choke balun and utilizes a bifilar pair designed to maximize inter winding breakdown voltage found on multiband antennas such as doublets and...

This is a departure from the normal 1:1 isolation/choke balun and utilizes a bifilar pair designed to handle the high voltages typically found on multiband antennas such as doublets and multiband...

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.

This is a balun originally designed by Guanella and subsequently improved by Dr. Jerry Sevick (W2FMI sk). By utilizing Thermaleze wire inserted in Teflon tubes, Dr. Sevick was able to substantially...

This is a great all purpose 4:1 current balun designed for those who would like the combination of a 4:1 balun capable of tolerating a compromised antenna installation and still provide a high level...
