12:1 Baluns/Ununs

BULLET Impedance Transformers (1:1, > 1:1)

BULLET format transformers are made in ratios from 1:1 up to 16:1 in 100/500/1500/5000 watt PEP Models. We also make BULLET Hybrids of NN:! + 1:1 in the same enclosure.

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.
