4:1 Baluns (200 to 50 ohms)

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...

In an effort to provide a 4:1 current balun with the tolerance of the model 4113 and the transformation attributes of the model 4115, Balun Designs is offering the model 4114ocf.  By utilizing our stacked core design, we create a 4:1 current...

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 design is built by winding individual cores as 1:1 choke baluns (100 ohm characteristic impedance) and then cross connecting them.  This creates a 4:1 current balun with excellent feedline isolation, very high...

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...

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...
