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).
RFI/EMI Solutions from KHz to GHz
The Ferrite Snap On, Ring and slip on sampler Pack is a convenient solution for
troubleshooting RFI/EMI with various diameter cables ranging from 1/4″
to 1.4″ for use as either single turn or multiple turn ferrite chokes using ferrite rings, slip on beads and snap on beads.
The filters are useful for RF coax, AC/DC power cables, and device interconnection cables.
Always use a snap on or ring with a larger inside diameter than the diameter of the cable and use multiple turns if possible (2 turns through the snap on is the same as 4 snap ons with 1 turn). Included in these combo packs are our most popular snap on sizes as follows:
F240-31 ring – 1.4 inch ID – 2 pieces
FSB31-1/4 – 1/4 inch ID – 4 pieces
FSB31-3/8 – 3/8 inch ID – 4 pieces
FSB31-1/2 – ½ inch ID – 4 pieces
FSB31-3/4 – 3/4 inch ID – 2 pieces
