Simple Jumper Feed Line Choke

The simplest, most cost effective feed line choke is a ferrite ring installed as shown in the picture (at the antenna feed point) to stop feed line radiation or at the radio end of the coax to suppress common mode coax noise current on the coax braid.

Improves antenna pattern by preventing your dipole from becoming a tripole

Suppresses pesky coax braid radiation and RFI

Reduces coax braid common mode current up to -30 dB ( 6 "S" units) on receive

Use one choke for each antenna feed line

Add a double female barrel connector to act as an "extension" of the existing coax.

Magnetic Loop Users: use 1 JC-1-1500 at the antenna feed point to keep all of transmit power on antenna and another at radio end to remove common mode noise received on the coax braid.

Need the ring only and not the jumper, select F240-31-1 as the part #.

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.
