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 and excellent return loss for those who want high...

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...

This is a departure from the normal 1:1 isolation/choke balun and utilizes a bifilar pair designed to maximize inter winding breakdown voltage. This is a departure from the normal 1:1 isolation/choke balun and utilizes a bifilar pair designed to maximize...

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 loops. The balun functions to transform balanced twin...

This balun is an excellent step up from the model 4113 and is not sensitive to high power reflected RF like the model 4115.  The design is the perfect choice for two types of operation.  First, if you transmit high power (=>1kW) in to a...

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 conductors and...

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 of performance. This unit is a great choice for...
