- Works for coax fed antennas from 1.8-61 MHz (160-6 meters)

- 2-5 times more wider bandwidth and higher power then competing baluns of similar power ratings


This balun has a SO-239 input and 1/4" top studs output.

For Higher Power needs use our CB-9-1500TS or CB-9-5000TS

12:1 Baluns are useful between 600-650 ohm balanced loads the impedance at the  end of the feed line is 600 ohms (1/2 wavelength feed line), or high impedance feeds for rhombic,  T2FD and traveling wave antennas.

12:1 Ununs are useful between coax and long wires with a load impedance near 600 ohms like a beverage antenna.  Shortwave listener antennas also can benefit with the 12:1 unun and it may provide a better match than 9:1 ununs – this means quieter noise levels and stronger signals so you can hear distance stations easier.
