Ferrite Ring Toroid Core, ID = .9"/23mm, Mix 43

Excellent for impedance transformers like 2:1, 4;1, 9:1 or use our convenient Balun/Unun DIY kits with all the parts needed.

 

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.
