Note this "split bead" comes in two halves which are tie wrapped or taped together. Due to the longer length of the split bead halves, the impedance is higher than other similar mix split beads. Useful for large bundles of wire or cables or coaxial feed lines.

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).
