<P> Early satellite television systems were not very popular due to their expense and large dish size . The satellite television dishes of the systems in the late 1970s and early 1980s were 10 to 16 feet (3.0 to 4.9 m) in diameter, made of fibreglass or solid aluminum or steel, and in the United States cost more than $5,000, sometimes as much as $10,000 . Programming sent from ground stations was relayed from eighteen satellites in geostationary orbit located 22,300 miles (35,900 km) above the Earth . </P> <P> By 1980, satellite television was well established in the USA and Europe . On April 26, 1982, the first satellite channel in the UK, Satellite Television Ltd. (later Sky1), was launched . Its signals were transmitted from the ESA's Orbital Test Satellites . Between 1981 and 1985, TVRO systems' sales rates increased as prices fell . Advances in receiver technology and the use of Gallium Arsenide FET technology enabled the use of smaller dishes . 500,000 systems, some costing as little as $2000, were sold in the US in 1984 . Dishes pointing to one satellite were even cheaper . People in areas without local broadcast stations or cable television service could obtain good - quality reception with no monthly fees . The large dishes were a subject of much consternation, as many people considered them eyesores, and in the US most condominiums, neighborhoods, and other homeowner associations tightly restricted their use, except in areas where such restrictions were illegal . These restrictions were altered in 1986 when the Federal Communications Commission ruled all of them illegal . A municipality could require a property owner to relocate the dish if it violated other zoning restrictions, such as a setback requirement, but could not outlaw their use . The necessity of these restrictions would slowly decline as the dishes got smaller . </P> <P> Originally, all channels were broadcast in the clear (ITC) because the equipment necessary to receive the programming was too expensive for consumers . With the growing number of TVRO systems, the program providers and broadcasters had to scramble their signal and develop subscription systems . </P> <P> In October 1984, the U.S. Congress passed the Cable Communications Policy Act of 1984, which gave those using TVRO systems the right to receive signals for free unless they were scrambled, and required those who did scramble to make their signals available for a reasonable fee . Since cable channels could prevent reception by big dishes, other companies had an incentive to offer competition . In January 1986, HBO began using the now - obsolete VideoCipher II system to encrypt their channels . Other channels uses less secure television encryption systems . The scrambling of HBO was met with much protest from owners of big - dish systems, most of which had no other option at the time for receiving such channels, claiming that clear signals from cable channels would be difficult to receive . Eventually HBO allowed dish owners to subscribe directly to their service for $12.95 per month, a price equal to or higher than what cable subscribers were paying, and required a descrambler to be purchased for $395 . This led to the attack on HBO's transponder Galaxy 1 by John R. MacDougall in April 1986 . One by one, all commercial channels followed HBO's lead and began scrambling their channels . The Satellite Broadcasting and Communications Association SBCA was founded on December 2, 1986 as the result of a merger between SPACE and the Direct Broadcast Satellite Association (DBSA). </P>
