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!).
Use for DSL/cable modems, routers, access points, repeaters, Ethernet switches, etc.
The RFI-ROUTER-4 kit is meant to be used with a DSL Modem/Router with incoming DSL signal, up to 4 Ethernet lines and a single power DC power supply line coming into the device.Included are one snap on ferrite (3/4” hole) and two (3/4” hole) snap on split ferrite beads for the Ethernet outputs (2 per snap on using multiple turns for each cable). The additional 3/4" snap on is for the power supply line. The RFI-ROUTER-8 kit is identical but has 2 additional ferrite snap on for up to 4 additional ports,
Useful for all brands of computer equipment.
