Balun Hybrids include an impedance balun (2:1, 4:1, 6:1, 9:1, 16:1, etc) and a 1:1 balun (choke) in a single enclosure. Use on OCF, loop, terminated dipoles and similar coax fed antennas requiring an impedance transformer Suppresses common mode current on the coax outer braid (prevents your dipole from acting as a tripole!).
This Ferrite Ring and Snap On Combo Pack features our two most popular ferrite filter sizes - the 1.4" ID ring for multiple turns of AC/DC or signal cables and the 1/2" ID snap on for signal cables like ethernet, audio, video, coax or data cables. You get 10 of the rings and ten 1/2" snap on ferrites - plenty to solve a complex RFi problem or several smaller ones.
The filters are useful for RF coax, AC/DC power cables, 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).
Combo Pack includes the following:
F240-75 ring – 1.4″/35.6mm ID – 10 pieces
FSB75-1/2 – 1/2″/12.7mm ID – 10 pieces
Normal Retail price is $215 for these parts
