Excellent for large cables or multiple cables – use multiple cores for higher choking. Also useful when you need high turns count for high choking with large cable - works on large gauge DC power cables.

Note: put both positive and negative cables TOGETHER through the filter so that their differential currents cancel but their common mode currents are suppressed.

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.
