Typical transponders each have a bandwidth between 27 and 50 MHz. Each geostationary C-band satellite needs to be spaced 2° longitude from the next satellite to avoid interference; for K u the spacing can be 1°. This means that there is an upper limit of 360/2 = 180 geostationary C-band satellites or 360/1 = 360 geostationary K u-band satellites.
In November 1990, Primestar launched as the first North American direct-broadcast satellite service. Hughes's DirecTV, the first national high-powered upper K u-band satellite TV system, went online in 1994. The DirecTV system became the new delivery vehicle for USSB.

The satellite communications portion of the C band is highly associated with television receive-only satellite reception systems, commonly called "big dish" systems, since small receiving antennas are not optimal for C band. Typical antenna sizes on C-band-capable systems range from 6 to 12 feet (1.8 to 3.5 meters) on consumer satellite dishes ...
In this plan, PBS would continue to lease four C-band transponders starting in 1991, with the goal being to convert their satellite operations to Ku-band sometime in 1993 or 1994. [24] In 1991, PBS purchased C-band transponder space on the Spacenet 1 satellite, owned by GTE, at orbital position 120°W. [9] This move occurred on January 3, 1991.
At this time, the vast majority of analog satellite TV transponders still were not encrypted. [13] On November 1, 1988, NBC began scrambling its C-band signal but left its K u band signal unencrypted in order for affiliates to not lose viewers who could not see their advertising. Most of the two million satellite dish users in the United States ...
In Brazil the main FTA satellite is the Star One D2, it holds approximately C-band analog channels (1985-2024), including all major networks like TV Globo (feed SP1 digital HDTV), SBT (feed nacional digital HDTV), Record (feed nacional digital HDTV), Record News (feed nacional digital HDTV), RFTV (feed nacional digital HDTV), RedeTV!, Band ...
The company was formed in 1980 as EchoStar Communications by Charlie Ergen, Candy Ergen, and Jim DeFranco, as a distributor of C-band satellite television systems. [2] In 1987, EchoStar applied for a satellite television broadcast license with the FCC and was granted access to orbital slot 119° west longitude in 1992.
