The DirecTV satellite fleet is a group of communications satellites located at various geostationary orbits that DirecTV uses for their satellite television service and HughesNet (formerly known as DirecWAY and DirecPC) internet service. The "DirecTV" prefix in their names has been changed to "T".
The T14 satellite is the sixth satellite built by SSL (Space Systems/Loral) for operator DirecTV. The high-capacity spacecraft is based on the SSL 1300 platform, T14 is a 20-kilowatt class Ka-band and reverse-band digital broadcast satellite that will be used to deliver Ultra HD and other new consumer services for DirecTV.
T10 (formerly DirecTV-10) is a Boeing model 702 direct broadcast satellite that provides high-definition television (HDTV) to DirecTV subscribers in North America. [1] It was launched by International Launch Services on July 7, 2007 from the Baikonur Cosmodrome in Kazakhstan aboard an Enhanced Proton Breeze-M rocket. [2]
For an ideal uniformly illuminated parabolic reflector and θ in degrees, k would be 57.3 (the number of degrees in a radian). For a typical parabolic antenna, k is approximately 70. [14] For a typical 2 meter satellite dish operating on C band (4 GHz), this formula gives a beamwidth of about 2.6°.
In electromagnetics, directivity is a parameter of an antenna or optical system which measures the degree to which the radiation emitted is concentrated in a single direction. It is the ratio of the radiation intensity in a given direction from the antenna to the radiation intensity averaged over all directions. [ 1 ]
As of the end of Q1 2021, AT&T had 15.9 million pay-TV customers, including DirecTV, U-Verse, and DirecTV Stream subscribers. [5] On February 25, 2021, AT&T announced that it would spin-off DirecTV, U-Verse TV, and DirecTV Stream into a separate entity, selling a 30% stake to TPG Inc., while retaining a 70% stake in the new standalone company ...
Patch antenna gain pattern. A directional antenna or beam antenna is an antenna which radiates or receives greater radio wave power in specific directions. Directional antennas can radiate radio waves in beams, when greater concentration of radiation in a certain direction is desired, or in receiving antennas receive radio waves from one specific direction only.
Range recommendations from manufacturers are the most modest of the groupings. For the minimum (or nearest) viewing distance, they recommend a view angle of approximately 31 degrees; and for the maximum, a view angle as low as 10 degrees. [35] [36] A 10-degree view angle is approximately the angle that NTSC television was typically viewed from ...
