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 dipoles typically at or above 60 feet horizontal. By utilizing Thermaleze wire inserted in teflon tubes, this model substantially increases the breakdown voltage between both conductors and windings while insuring the 100 ohm characteristic impedance of the windings.
If you are building a 160m OCF dipole and it will be above 60-70 feet, the 4:1 balun (Model 4114, 4115 or 4116) has shown to provide a better overall match. The 6:1, model 6113 should be used if the OCF will be cut for an 80m length or less and the feedpoint will be at or above 60 feet.
|Core Material|| Custom mix low permeability ferrite by Fair Rite Products for maximum bandwidth.
Large 2.4 inch cores are coated and sealed for long term durability.
|Winding Type|| Individual cores wound with bifilar pairs to create two 4:1 current baluns.
The two baluns are then cross connected in series/parallel to create 6:1 current balun.
|Winding Material|| Bifilar windings of 14 gauge Heavy build polyamideimide Allex 240 Winding Wire.
Windings are inserted into Teflon tubes increasing total breakdown to 10,000 volts.
|Power Rating|| 3..5 to 35 MHz - 3kW, 35 to 54 MHz - 2kW.
All ratings based on resonant load. High SWR will reduce power handling ability.
|Useable Frequency||3.5 to 54 MHz|
|Insertion Loss|| Less than 0.2db
|Connectors|| SO-239 connectors are silver plated with Teflon insulation.
Studs and eyebolts are 1/4 inch.
Alternate connectors and Mounting Options are available in the Accessories section.
|Hardware||All Stainless Steel|
| Enclosure Type
|| NEMA rated 4x marine grade junction box for outdoor installations.
Cover utilizes integral neoprene gasket for weatherproof integrity.
|Dimensions|| 4x4x2 inches for main body of unit
Dimensional Drawing of Standard Enclosure
|Additional Info|| Very high efficiency.
Will not heat up or saturate at like many of the "less expensive" designs.
