Ferrite Slip On Bead, ID = .505in/12.8mm, Mix 31, 1 piece - very useful for making feed line chokes for RG-213 (1/2") coax line.

These beads fit well on 1/2" coax cable and make excellent sleeve chokes (See BA-8-5 for sample graphs pf effectiveness)

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.
