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...

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...

Building on the original 1:1 design by Dr. Jerry Sevick, this balun has two (2) low permeability cores in a stacked configuration to maximize choking impedance on HF bands from 7- 54MHz. By utilizing Mil-Spec coax, the SWR, transformation and power...

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

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...

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...
