Slow-scan television (SSTV) is a picture transmission method, used mainly by amateur radio operators, to transmit and receive static pictures via radio in monochrome or color. A literal term for SSTV is narrowband television .
For example, in the United States, the Telecommunications Act of 1996 (Over-the-Air Reception Devices OTARD Rule) allows "any owner or a tenant" [24] the right, "on property that they own or over which they have exclusive use or control", [24] to install "An antenna that is designed to receive local television broadcast signals" but that "masts ...
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 satellite dish is a dish-shaped type of parabolic antenna designed to receive or transmit information by radio waves to or from a communication satellite. The term most commonly means a dish which receives direct-broadcast satellite television from a direct broadcast satellite in geostationary orbit .
Owners of cable systems paid $10,000 to install 3-meter dishes to receive TV signals in C band. In 1976 Taylor Howard built an amateur system, which consisted of a converted military surplus radar dish and a satellite receiver designed and built by Howard, for home satellite reception.
A transmatch (antenna tuner) is not required to use this antenna near its nominal design frequency of 14 MHz, and judicious length adjustments can sometimes include one other frequency band. All other frequencies require a transmatch. [citation needed] There are many variants of the G5RV antenna. Two variations of the G5RV design, called ZS6BKW ...
A SMATV headend is used to receive and rebroadcast satellite television channels throughout a property from a single satellite feed. [4] The system consists of a master antenna and a matching transformer to match the balanced antenna with unbalanced cable and amplifiers. [5] Most antennas have an impedance of around 300 Ω.
A secondary antenna has a greater beam width than the primary antenna and receives the same tracking signal from the satellite. The primary antenna is tracked according to a predetermined search pattern which causes a variation in the signal amplitude depending upon the relative location of the satellite and the antenna position.
