Snap On Sleeve Chokes
Connector already on the cable? Don’t want to remove it? Use Snap On Ferrite split bead kits that clamp over the cable.
SNAP ON Sizes for Heliax and Coax Cable
Shown in the table are the SLIP ON and SNAP ON products for various popular Heliax and coax cables. These are the correct size for making common mode chokes for coaxial cable using either Snap On ferrite beads.
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.
