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:
Off Center Fed (OCF) Antenna Feed Line Choke for 1/4" coax (1.8-61 MHz)
Got an off center fed antenna fed with RG-8X size coax and having feed line radiation (RFI) problems?
This feed line choke will help solve the problem of feed line radiation (which causes RFI to nearby object close to you coax) as well as Improving antenna pattern by preventing your dipole from becoming a tripole
Simple to install as an extension to your existing coax feed line using a female to female barrel connector (available separately).
Install quickly, reduce your coax radiation issues and start working more DX with a better transmission (and reception) antenna pattern.
Also works with single or multi-band loop antennas using a 2:1, 4:1 or 6:1 transformer without a choke.
