During the 1960s, dish antennas became widely used in terrestrial microwave relay communication networks, which carried telephone calls and television programs across continents. [17] The first parabolic antenna used for satellite communications was constructed in 1962 at Goonhilly in Cornwall, England, to communicate with the Telstar satellite.
The NS3000 Satellite Modem modulates and demodulates data and video signals transmitted via satellite. The "IP modem" (satellite modem) developed and made by Newtec of Belgium for SES' 2Mbit/s ASTRA2Connect European two-way satellite Internet system. Satellite modems are often used for home internet access.
