This 6:1 current balun is another new addition to the Balun Designs line of quality products. By utilizing Thermaleze wire inserted in teflon tubes, this model substantially increases the breakdown voltage between both conductors and windings while improving the overall input impedance.
Using two (2) 4:1 Current baluns in parallel with one reversed, a 6:1 design is created that will handle very high power from 1mhz to 30mhz. It's a perfect choice to feed multiband antennas such as off center fed dipoles, Windoms and any other high input impedance antennas.

Key Design Features:
Special mix toroids with low permeability coated with epoxy paint for extra durablity.
Design has excellent broadband frequency response and is very efficient (98-99%).
Typical SWR is below 1.1 : 1 with excellent Transformation and return loss exceeding -30db.
2 separate bifilar windings of 14 gauge Thermaleze wire wound on two separate cores. This is NOT the enameled type (Formvar) used by my less expensive competitors. It is coated with a polyimide covering rated at a minimum of 2000v breakdown voltage. The windings are then inserted into teflon tubes which increases the total breakdown to 10,000 volts.
Typical insertion loss is < 0.2db
SO-239 connectors are silver plated with teflon insulation and gold center conductor.
All hardware is Stainless Steel. Eyebolts and studs are 1/4"
N connector and Alternate mounting options are available in Accessories.
Because of the high efficiency, this balun will not heat up or saturate like the typical cheap current baluns using ferrite rods, beads or open air wound coax.
The balun is installed in a weatherproof 4" X 4" X 2" NEMA Box with only small weep holes at the base to allow escape of condensation. Balun should always be mounted with the SO-239 in the down position.
This balun will handle continuous power of 3kw (6kw PEP) and tolerate high SWR for extended periods.
It will not heat up at rated power, using extended duty cycles or stressing load conditions.
You can see from the pictures there are three versions. One with closed eye loops to provide anchors for dipoles or with studs for use with quads and loops. The enclosure has four legs on the back side which can be used to mount to the Balun Designs mounting plate for mast or boom mounting. The balun can also be built with studs on top of the enclosure for connection to ladder line, to use with yagis or any other design that requires this connector configuration.
