Product Details
MPN: JC-1-5000
Country/Region of Manufacture: USA
Simple Hi Power 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 -25 dB ( 4 "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.
UHF (PL-259) Connectors on each end
DIY with your own coax with a FSB31-1-1 ferrite snap on (1-300 MHZ)

Typical user comment:
The filter was quite effective. Was surprised that it actually reduced the noise level more than the signal so S+N/N improved by 1.9 S units. Bill
