Excellent for high power broadband RF transformers, RFI common mode noise suppression, AC/DC power cable suppression of high frequency harmonics, Bulk Pack of 10 rings.
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).
