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.
[citation needed] As of 2009, there are 23 C-band satellites and 38 K u /K a band satellites. [17] There were over 150 channels for people who want to receive subscription channels on a C-band dish via Motorola's 4DTV equipment via two vendors Satellite Receivers Ltd (SRL) and Skyvision Archived January 13, 2011, at the Wayback Machine.

The majority of ethnic-language broadcasts in North America are carried on K u band free-to-air. The largest concentration of free-to-air programming is on Galaxy 19 at 97° W. Pittsburgh International Telecommunications and GlobeCast World TV offers a mix of free and pay-TV ethnic channels in the internationally standard DVB-S and S2 formats ...
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.
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 nacional digital HDTV), SBT (feed nacional digital HDTV), Record (feed nacional digital HDTV), RedeTV!, Band (feed nacional digital HDTV), Cultura, Futura (feed nacional digital HDTV ...
The network is also available nationwide on free-to-air C-band satellite via SES-2 in DVB-S2 format; [2] [3] as individualized transmitter-ready feeds for each station are centrally generated using broadcast automation and delivered to the stations by satellite. In March 2020, Retro TV launched a live online feed, which carries a limited six ...
A Viewsat Xtreme FTA receiver. A free-to-air or FTA Receiver is a satellite television receiver designed to receive unencrypted broadcasts. Modern decoders are typically compliant with the MPEG-4/DVB-S2 standard and formerly the MPEG-2/DVB-S standard, while older FTA receivers relied on analog satellite transmissions which have declined rapidly in recent years.
One use of the C band is for satellite communication, whether for full-time satellite television networks or raw satellite feeds, although subscription programming also exists. This use contrasts with direct-broadcast satellite , which is a completely closed system used to deliver subscription programming to small satellite dishes that are ...
