For impedance transformation/isolation applications when max power is < 10 Watts PEP, this transformer provides a simple interface between transmission lines with different connectors or impedances or simply common mode isolation. DC continuity for bias-T applications.
Simple Jumper Feed Line Choke with 3 FT "tail" for other connections
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.
Need the ring only and not the jumper, select F240-31-1 as the part #.
