Broadcast signal intrusion

A broadcast signal intrusion is the hijacking of broadcast signals of radio, television stations, cable television broadcast feeds or satellite signals without permission or licence. Hijacking incidents have involved local TV and radio stations as well as cable and national networks.

This article is about the hijacking of broadcast signals. For the 2021 film, see Broadcast Signal Intrusion.

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.
