Category:Signal Intrusion

A Signal intrusion is the hijacking of broadcast signals of radio, television stations, cable television broadcast feeds or satellite signals without permission nor license. Hijacking incidents involve local TV and radio stations as well as cable and national networks.

Although television, cable and satellite broadcast signal intrusions tend to receive more media coverage, radio station intrusions are more frequent, as many simply rebroadcast a signal received from another radio station. All that is required is an FM transmitter that can overpower the same frequency as the station being rebroadcast.

Other methods that have been used in North America to intrude on legal broadcasts include breaking into the transmitter area and splicing audio directly into the feed. As a cable television operator connects itself in the signal path between individual stations and the system's subscribers, broadcasters have fallen victim to signal tampering on cable systems on multiple occasions.
