The TRIA is the part of the antenna which contains both the feed horn and the circuits which convert high-frequency satellite signals such as X-band, Ku-band and Ka-band to and from the L-band microwave signals used for transmission between the dish and the customer-premises equipment.
A satellite dish is a dish-shaped type of parabolic antenna designed to receive or transmit information by radio waves to or from a communication satellite. The term most commonly means a dish which receives direct-broadcast satellite television from a direct broadcast satellite in geostationary orbit .
An antenna farm, satellite dish farm or dish farm is an area dedicated to television or radio telecommunications transmitting or receiving antenna equipment, such as C, K u or K a band satellite dish antennas, UHF/VHF/AM/FM transmitter towers or mobile cell towers.
A Tier-1 satellite dish (manufactured by Level 3 Communications) in Boise, Idaho. In Federal Standard 1037C, the United States General Services Administration defined an Earth terminal complex as the assemblage of equipment and facilities necessary to integrate an Earth terminal (ground station) into a telecommunications network.
A polar mount is a movable mount for satellite dishes that allows the dish to be pointed at many geostationary satellites by slewing around one axis. [1] It works by having its slewing axis parallel, or almost parallel, to the Earth's polar axis so that the attached dish can follow, approximately, the geostationary orbit, which lies in the plane of the Earth's equator.
The radio transmitter aboard Telstar was very low-powered compared to modern communication satellites, with a power of only 14 watts, and transmitted through an omnidirectional antenna, so the ground antennas that communicated with it had to be huge, with very large apertures to receive enough radio power from the satellite to be intelligible.
