* Important: Antennas are not rated for AM, RTTY or other high duty-cycle modes. The power rating is for normal SSB and CW duty-cycles only.

Exception: At transceiver output levels, all antennas rated for 1500 watt service may be used on PSK-31 and similar modes without sacrificing low IMD specifications.

Applications:

Dipoles, trap dipoles, Inverted-V, etc. Any application requiring a 50 or 75 ohm balun.


The B1-2K follows the same tradition of the uncompromising performance established by the incomparable C1 and B4 baluns. The B1-2K is built into a conventional case with eyebolts. It is here the similarity with other products ends. The B1-2K is a high power balun. There cores are over twice the size of other manufacturer's baluns. Only the RADIO WORKS' design brings the wires from the balun's windings directly outside the case so you may solder them directly to the antenna wire.

With the introduction of newly developed ferrites operating in both the HF and VHF regions, it is now possible, with new winding techniques, to build a balun which covers an additional octave of bandwidth. The result is the B1-2K Plus which efficiently covers 80 - 6 meters with excellent performance.

Direct connection between the balun's windings and the antenna's elements means there is no chance of an intermittent connections.

Eye-bolts are stainless-steel and the entire assembly is built for long life.

The B1-2K Balun is perfect for any wire antenna with 50 ohm coaxial feed.
