GENERIC HOUSEHOLD RADIO FREQUENCY INTERFERENCE (RFI) KIT
The RFI kit is designed to cure most household RFI problems. It contains ferrite toroids and 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.
What is in the kit? Three 1/2" ID snap on beads, three 1/4" snap on beads, 3 wall wart filter rings to suppress noise and interference and a large 1.4" ID ring for AC power cord installation on RFI prone equipment like computers, Home Theater Systems, telephones, etc.
Plus full instructions in the RFI TipSheet. A $49.50 retail value if purchased separately.
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.
