Excellent for impedance transformers like 2:1, 4;1, 9:1 or use our convenient Balun/Unun DIY kits with all the parts needed.

2:1 (100:50) Baluns are useful between 50 ohm coax and 100 ohm balanced lines for loops, cubical quads, log periodics and other antennas where the impedance at the end of the feedline is 100 ohms (1/2 wavelength feedline).
