Mix 31 Ferrite Snap On Combo pack (RFI Suppression range is 1-300 MHz)

The Ferrite Snap On Combo Pack is a convenient solution for troubleshooting RFI/EMI with various diameter cables ranging from 1/4″ to 3/4″ for use as either single turn or multiple turn ferrite chokes.

The snap on chokes are useful for RF coax, AC/DC power cables, and device interconnection cables.

Always use a snap on ferrite 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 turns in series).

Included in the combo pack are our most popular snap on sizes as follows:

FSB31-1/4 – 1/4″ ID – 6 pieces

FSB31-3/8 – 3/8″ ID – 6 pieces

FSB31-1/2 – 1/2″ ID – 6 pieces

FSB31-3/4 – 3/4″ ID – 4 pieces


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.
