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.
Great choke for log periodics, HF beams, Transceiver/Amp isolation
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 -40 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.
SIGNALCUBE RF Detector, 60 Hz - 1.2 GHz, Miliwatts to Kilowatts, Light Detector, Easy Antenna Check, No Battery!
The smaller version of the Signalsquare, but functions the same. Encased in a protective case that can handle outdoor environments. A water proof device to detect RF signals without a battery. You can attach this to any base stations and uses RF as a power source to light up an indicating light.
