This QRP balun is wound with mil spec Teflon insulated coax which provides a consistent 50 impedance for the windings. The design provides high levels of feedline isolation, RF choking and excellent return loss for those who want top...

This QRP balun is the newest in our low power 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...

We're bring back one of Dr. Jerry Sevick's (W2FMI) original designs but with upgraded windings.  This balun was one of our original workhorses and now with new coaxial windings, provides a single core balun optimized for 40 -10m.  By using our...

Balun Designs, in collaboration with Fair Rite products, has developed what we consider to be the best single core 1:1 feedline isolation balun available today. By reviewing the scans shown below you can see what we're referring to.  Notice how the...

Designed for those who want the maximum isolation and choking across the full HF spectrum. Building on the original 1:1 design by Dr. Jerry Sevick, this balun has two (2) cores in a stacked configuration to maximize choking impedance on HF bands from 1-...

This Isolation balun is an identical design to the Model 1115d with one key exception. The material utilized for the two stacked cores is optimized for the lower HF bands and provides exceptional choking impedance at these frequencies. In...

This new release provides excellent choking and feedline isolation across the full HF spectrum, but is a departure from the normal 1:1 isolation/choke balun.  Rather than a 50 ohm characteristic impedance, this balun utilizes a bifilar pair designed...

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 maximize inter winding breakdown voltage.found on multiband antennas such as doublets and multiband loops. The balun functions to transform balanced...

Excellent broadband balun that can be used anywhere there is a need to transform 75 ohms balanced to 50 ohms unbalanced. Its most common use is at the feedpoint of monoband dipoles that have an impedance of 72-75 ohms.  This is a...

This is a another excellent broadband design that can be used anywhere there is a need to transform 125 ohms balanced to 50 ohms unbalanced. It can be used at the feedpoint of a coaxial fed multiband loop as described below, but...

This model is the very useful 4:1 current balun, one of the most versatile ratios for a low power balun. Great for off center fed dipoles, ladder line fed multiband dipoles etc. Extremely compact and light weight with alternative connectors...

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 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...

Heavy duty 4:1 tuner balun utilizing stacked cores to provide a very high power rating across all HF frequencies.  Constructed using our enhanced design with Teflon tubing over heavy build Thermaleze insulated wire. If you are...

Utilizing two (2) individually wound 4:1 current baluns cross connected in series/parallel, a 6:1 design is created that will handle high power from 3.5 to 54 MHz. Good choice to feed multiband antennas such as off center fed...
