This is a unique 1:1 transmission line transformer intended to provide highest possible isolation between input and output.  Consequently there is no direct electrical connection between the input and output with all RF energy being...

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 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...

Jerry Sevick (W2FMI) specifically researched and designed this tuner balun to provide a very constant 50 ohm input impedance on the lower frequencies where most baluns can drop by 20-40%.  In addition, the Thermaleze wire/Teflon tube windings on a...

Balun Designsis now offering this low power alternative in a stacked core configuration for those who want to use an End Fed Half Wave for portable or temporary installations.  Built with the same craftsmanship as all our other units, this new model...

For those that enjoy the LNR and Hy Endfed antennas, but want to run more power, Balun Designs now offers an excellent alternative.  Built with the same craftsmanship as all our other units, this new model will allow you to either replace your...

Balun Designs now offers an excellent reduced power version of our popular model 49131.  Built with the same craftsmanship as all our other units, this new model will allow you to either replace your current matching unit or construct a new medium...

For those that enjoy half wave end fed antennas but want to run more power, Balun Designs now offers an excellent alternative.  Built with the same craftsmanship as all our other units, this new model will allow you to either replace your current...

While primarily designed for use with a "Loop on Ground" antenna, this is an excellent 9:1 isolation balun for any receive application.  Separate input and output windings provide a high level of isolation and noise reduction plus, to maximize...
