The Minidish is the tradename used for the small-sized satellite dish used by Freesat and Sky. The term has entered the vocabulary in the UK and Ireland as a generic term for a satellite dish, particularly small ones. [citation needed] The Minidish is an oval, mesh satellite dish capable of reflecting signals broadcast in the upper X band and K ...
The prevention of piracy on cable and satellite networks has been one of the main factors in the development of Pay TV encryption systems. The early cable-based Pay TV networks used no security. This led to problems with people connecting to the network without paying. Consequently, some methods were developed to frustrate these self-connectors.
A skip zone is an annular region between the farthest points at which the ground wave can be received and the nearest point at which the refracted sky waves can be received. Within this region, no signal can be received because, due to the conditions of the local ionosphere, the relevant sky waves are not reflected but penetrate the ionosphere.

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.
Satellite television, like other communications relayed by satellite, starts with a transmitting antenna located at an uplink facility. [7] Uplink satellite dishes are very large, as much as 9 to 12 meters (30 to 40 feet) in diameter. [7] The increased diameter results in more accurate aiming and increased signal strength at the satellite. [7]
A photo of all three BSB dishes available, the squarial, a Sky dish for comparison, the round BSB dish, and the square BSB dish. Unlike a normal satellite dish, which uses a parabolic reflector to focus the radio waves on a single feed horn antenna, the Squarial was a phased array antenna, a common design in which multiple small antennas work together to receive the waves.

For long delay multipath, the receiver itself can recognize the wayward signal and discard it. To address shorter delay multipath from the signal reflecting off the ground, specialized antennas (e.g., a choke ring antenna) may be used to reduce the signal power as received by the antenna. Short delay reflections are harder to filter out because ...
