1:2 Unun (25 to 50 ohms) 5kw #1235 Manufacturer: Balun Designs SKU: 1235 Price: $98.95 Quantity:

This is one of several new UNUN's being added to the Balun Designs line of quality products. These designs are excellent for matching antennas such as inverted L's, vertical wires and other low feedpoint impedance designs.  Although simple in appearance the build of this unun is quite complex hence the higher price.  Windings for this model feature custom HAND made coax to provide high power capability at low impedance.

Unlike Baluns, Unun's (unbalanced to unbalanced) provide impedance transformation for antennas that are naturally unbalanced because of their construction configuration. Even though some unun's appear small is size, they are able to handle very high power (matched condition) because of their excellent efficiency.

25 to 50 ohms

Many other unun ratios are available by contacting me via the methods shown in Support.

Design Features:

• Special mix toroid with low permeability. Toroid is also coated with epoxy paint for extra durability.
• Design has excellent broadband frequency response and is very efficient (99%).
• Windings of bifilar custom made low impedance coax.
• 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"
• The balun is installed in a weatherproof 4" X 4" X 2" NEMA Box that are excellent for outdoor and/or remote installations.
