2-way DiSEqC switch 4-way DiSEqC switch with attached coaxial cables.. DiSEqC (/ ˈ d aɪ s ɛ k, d aɪ ˈ s ɛ k s i /; [citation needed] short for Digital Satellite Equipment Control) is a special communication protocol for use between a satellite receiver and a device such as a multi-dish switch or a small [1] dish antenna rotor.
Special LNBs have been developed for use in single-cable distribution systems. All four sub-bands of the Ku band (low frequency/horizontal polarity, high frequency/horizontal polarity, low frequency/vertical polarity, high frequency/vertical polarity) are received by a conventional front end, amplified and downconverted to the L-band, to be fed to a number of SatCR (Satellite Channel Router ...
LNBs for fibre satellite distribution systems operate in a similar way to conventional electrical LNBs, except that all four of the sub-bands in the entire K u band spectrum of 10.70–12.75 GHz across two signal polarisations are simultaneously block-downconverted (as in a quattro LNB).
a Multiswitch with 16 outputs, the four cables from the Quattro-LNB enter on the left. A multiswitch is a device used with a dual or quattro LNB to distribute satellite TV signals to multiple (usually more than four) receivers from a single dish and LNB.
Power dividers (also power splitters and, when used in reverse, power combiners) and directional couplers are passive devices used mostly in the field of radio technology. They couple a defined amount of the electromagnetic power in a transmission line to a port enabling the signal to be used in another circuit.
Digital Video Broadcasting - Satellite - Second Generation (DVB-S2) is a digital television broadcast standard that has been designed as a successor for the popular DVB-S system. It was developed in 2003 by the Digital Video Broadcasting Project, an international industry consortium, and ratified by ETSI (EN 302307) in March 2005.
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.
Originally built for PrimeStar, DirecTV acquired the satellite in its 1999 buyout of the company. [36] The satellite was relocated from 119° W to 72.5° W in 2004 and temporarily leased to Telesat for their Canadian BSS service. [37] [38] In July 2005, the satellite replaced DirecTV 6 at 110° W, where it has remained ever since. [21]
