Off Center Fed Dipoles

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 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...

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 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...

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...
