[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 antenna sizes on C-band-capable systems range from 6 to 12 feet (1.8 to 3.5 meters) on consumer satellite dishes, although larger ones also can be used. For satellite communications, the microwave frequencies of the C band perform better under adverse weather conditions in comparison with the K u band (11.2–14.5 GHz ), microwave ...
A typical satellite has up to 32 K u-band or 24 C-band transponders, or more for K u /C hybrid satellites. 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 great decrease of dish size also allowed satellite dishes to be installed on vehicles. [10] Dishes this size are still in use today. Television stations, however, still prefer to transmit their signals on the C-band analog with large dishes due to the fact that C-band signals are less prone to rain fade than K u band signals. [11]
G Sat's satellite dish Cignal's satellite dish. Satellite television in the Philippines began in 2001 when the first pay DTH service Dream Satellite TV was launched. In 2009, both Cignal and G Sat were launched on the NSS 11 broadcasting satellite. Later, these satellite TV providers began offering HD.
ABS-3's Ku-band coverage zone encompasses Taiwan, portions of mainland China, Vietnam and the Philippines. The 24 Ku-band transponders of the satellite may be commanded by ground control to combine into 12 high-powered transponders with 220-watt amplifiers for the purpose of broadcasting Direct-to-Home digital TV services.
Fourth channels initially obtained much of their programming from VCR videotapes, which were then played and retransmitted via coaxial cables to connected households with a subscription, and subsequently enjoyed massive growth after the late 1980s when the legalisation of Ku band satellite receptions in 1988 and private installations of C band ...
In 2006, Dream began to use Koreasat 5 as an additional main broadcast to the existing Agila II satellite transponder. Starting 2010 until 2011, Dream closed all of the transponders of Agila II (ABS-5/ABS-3) for its main broadcast, due to the fact that it was only 2 years left in the orbit. When all of the Dream Satellite channels were transferred to Koreasat 5, Dream announced customers
