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 .
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 .
Analog big-dish satellite television receivers may be re-purposed for inexpensively receiving ATV in this band. Such receivers can decode FM television when an outdoor antenna is connected to the LNB input. Due to the low cost and ease of repurposing old analog satellite receivers, this is the most popular band for FM amateur TV.
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]
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 ...
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 ...
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.
In June 2003, the satellite was relocated back to 101.2° W, as the satellite was incapable of providing service to Hawaii. [22] In July 2005, the satellite was relocated to 72.5° W, as the former satellite at that position (DirecTV 5) had moved to 110° W to replace DirecTV 6, which was approaching the end of its fuel life.
