Model 1213 - 1:2 Balun (25 to 50 ohms) 3kW
$128.95This is a unique design by Dr. Jerry Sevick (W2FMI) that combines a 25 ohm balun with a 1:2 unun for final transformation to 50 ohms. Used anywhere there is a need to transform 25 ohms balanced to 50 ohms unbalanced. We have eliminated...$128.95 -
Model 2113 - 2:1 Balun (100 to 50 ohms) 1.5 - 54 MHz - 3kW
$126.95Excellent broadband balun that can be used anywhere there is a need to transform 100 ohms balanced to 50 ohms unbalanced. Its most common use is at the feedpoint of quads and mono band loops allowing the elimination of matching networks...$126.95 -
Model 25113 - 2.5:1 Balun 1.5 - 54 MHz - 3kW
$126.95This 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...$126.95 -
Model 4110 - 4:1 Current Balun - 3.5 - 54 MHz - 300 Watts
$64.95This 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...$64.95 -
Model 4113 - 4:1 Current Balun 1.5 - 54 MHz 3kW
$82.95This 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...$82.95 -
Model 4114 - 4:1 Current Balun 1.5 - 54MHz 5kW
$94.95This 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...$94.95 -
Model 4114ocf - 4:1 Balun 1.5 - 54 MHz for OCF Dipole - 5kW
$96.95In 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...$96.95 -
Model 4115 - Dual Core 4:1 Current Balun 5kW 1 - 54 MHz
$113.95This 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...$113.95 -
Model 4115ocf - 4:1 for OCF Dipoles 1.5 - 54 MHz 5kW
$115.95This 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...$115.95 -
Model 4116 - 4:1 Hybrid Balun 1.5 - 54MHz 3kW
$114.95This 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...$114.95 -
Model 4124 - 4:1 Tuner Balun 1 - 45 MHz 5kW
$118.95Jerry 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...$118.95 -
Model 4125 - 4:1 Tuner Balun 1.5 - 54 MHz 5kW
$107.95Heavy 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...$107.95
