This Extra Large size Ring and Snap-On Combo Pack is our BEST VALUE and a convenient solution for troubleshooting RFI/EMI (1-300 MHz) with various diameter cables ranging from 1.4" to 1.4"/35.6mm for use as either single turn or multiple turn RFI filters. Great for Grab and Go portable operations or general RFI and noise suppression.

The filters are useful for RF coax, AC/DC power cables, Ethernet, data, audio/video and device interconnection cables.

Always use a snap on or ring 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 turn). Included in these combo packs are our most popular snap on sizes as follows:

16:1 Baluns are useful between 750-850 ohm balanced loads where the impedance at the  end of the feed line is 800 ohms (1/2 wavelength feed line), or high impedance feeds for rhombic,  T2FD and traveling wave antennas.

16:1 Ununs are useful between coax and long wires with a load impedance near 800 ohms like a beverage antenna.  Shortwave listener antennas also can benefit with the 16:1 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.
