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:
PURPOSE
These kits are designed to choke common mode currents going into or exiting from your Tuner Genius cables. Filters are supplied for the RF Input (s) RF Outputs, DC power and LAN input. The DC power line choke helps keep common mode current out of the power line which could cause interference to other devices connected to the same power line if not suppressed. The LAN cable choke keeps any RFI off the LAN cable input.
USE
RFI-AT-FLEX-TG Standard kit for tuners with SO2R option and RFI-AT-FLEX-TG3 for tuners with 3 antenna outputs option (1X3).
Note if you use other cables into the tuner such as PTT or otherwise, use FSB31-1/2 snap on ferrites for these lines and wind 2 or more turns thru center if possible. These ferrites sold separately.
