Generic Computer Equipment RFI Kits - use for desktop, laptop, DSL/cable modems, Ethernet, etc.
This RFI kit is specifically selected to cure most household computer device RFI problems. It contains 2 ferrite ring for AC or DC power supply protection and 8 Snap On ferrite 1/4" split beads selected to eliminate RFI from 1 to 300 MHz. The beads are easy to use, don’t require modification of the protected equipment and work in almost all cases, even when plug-in filters fail.
Useful for all brands of computer equipment.
Also make sure you connect a good RF ground to the transceiver ground post.
Note to Flex Radio users: Use snap on ferrites for firewire cable, speaker cable and mic cable, Ring ferrites for Antenna output and DC power.
For additional RFI suppression, use a feed line choke at the antenna to suppress common current on the coax feed line – see our store for feed line choke alternatives for use at the antenna.
If you use a linear amplifier we have RFI kits for linear amplifiers that help suppress RFI in your shack or in your neighbor’s house.
