Originally constructed as a 64 m dish in 1973 and enlarged in 1987. It is the largest steerable parabolic antenna in the Southern Hemisphere. It is used by NASA to communicate with Voyager 2; the only antenna remaining on Earth capable to do so. [8] The antenna weighs more than 3000 tonnes and rotates on a film of oil approximately 0.17mm thick.
As the pay-TV sector continues its downward spiral, DirecTV and Dish Network — two longtime rivals that have explored joining up at various times for years — may be headed to the altar.
The first satellite TV systems were a now-obsolete type known as television receive-only. These systems received weaker analog signals transmitted in the C-band (4–8 GHz) from FSS type satellites, requiring the use of large 2–3-meter dishes. Consequently, these systems were nicknamed "big dish" systems, and were more expensive and less ...
The company was formed in 1980 as EchoStar Communications by Charlie Ergen, Candy Ergen, and Jim DeFranco, as a distributor of C-band satellite television systems.

The station is one of three [5] satellite communication stations in the NASA Space Communications and Navigation (SCaN) program’s Deep Space Network (DSN), whose mission is to provide the vital two-way communications link that tracks and controls interplanetary spacecraft and receives the images and scientific information they collect.
As of February 20, 2010, three different NASA networks are used - the Deep Space Network (DSN), the Near Earth Network (NEN) and the Space Network/Tracking and Data Relay Satellite System (TDRSS). The DSN, as the name implies, tracks probes in deep space (more than 10,000 miles (16,000 km) from Earth), while NEN and TDRSS are used to ...
