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 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). Included in these combo packs are our most popular snap on sizes as follows:
Combo split bead kit for dual band antenna like 2 meters/450 MHz (J-poles, dual band verticals, etc) - 4 beads covers VHF and UHF band. Each set provides over 500 ohms of common mode resistance to keep antenna current off the coax and on the antenna for better radiation pattern and less coax radiation which can cause RFI to nearby electronics.
Simple to install at antenna feed point - just snap on!
