TVI choke balun
This filter is an effective tool for suppression of interferrence at radio and television equipment, when a strong transmitter is nearby. Often, the shielding of the coaxial cable from satellite or cable receiver system acts as an "antenna" for the most long-wave transmissions from a nearby transmitter. With this choke, the shield of the coaxial cable is effective from
Receiver decoupled. The filter is looped into the antenna input of the SAT or cable box.
