The 4DTV makes use of first-generation digital master feeds on several satellites and hundreds of channels. Therefore, a high quality signal is received, compared to other programming options that are typically compressed and re-uplinked. Being a C-band system, the 4DTV has the advantage of signal stability, great satellite footprint and no ...
In response to a Notice of Proposed Rulemaking of July 2018 from the US Federal Communications Commission (FCC) to make the 3.7 to 4.2 GHz spectrum available for next-generation terrestrial fixed and mobile broadband services, [5] the C-Band Alliance (CBA) was established in September 2018 by the four satellite operators—Intelsat, SES ...

4DTV was a system for picking up free and encrypted analog and digital satellite subscription channels. It also included an interactive guide. The product line included: 2700 Series: on screen displays, C/Ku switching, digital sound, satellite memory increases with the model number. 2600 Series: similar to 2400 except with on-screen displays.
[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.

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 first satellite television dishes were built to receive signals on the C-band analog, and were very large. The front cover of the 1979 Neiman-Marcus Christmas catalog featured the first home satellite TV stations on sale. [2] The dishes were nearly 20 feet (6.1 m) in diameter. [3]
