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 has developed the model 4114ocf.  By utilizing our stacked core technology, we created a 4:1...

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...

For those who would like the combination of a 4:1 balun capable of tolerating a compromised Off Center Fed Dipole or multiband loop installation and still provide a high level of performance, the model 4116 is the solution. As the title indicates, this...

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...
