   en.wikipedia.org/wiki/Transponder_(satellite...

   an input low-noise amplifier (LNA), designed to amplify the signals received from the Earth station (normally very weak, because of the large distances involved), a frequency translator (normally composed of an oscillator and a frequency mixer) used to convert the frequency of the received signal to the frequency required for the transmitted ...

4. Antenna amplifier - Wikipedia

   en.wikipedia.org/wiki/Antenna_amplifier

   In electronics, an antenna amplifier (also: aerial amplifier or booster) is a device that amplifies an antenna signal, usually into an output with the same impedance as the input impedance. Typically 75 ohm for coaxial cable and 300 ohm for twin-lead cable. An antenna amplifier boosts a radio signal considerably for devices that receive radio ...

   At an outdoor cable box on the subscriber's residence, the company's service drop cable is connected to cables distributing the signal to different rooms in the building. At each television, the subscriber's television or a set-top box provided by the cable company translates the desired channel back to its original frequency ( baseband ), and ...

6. Low-noise block downconverter - Wikipedia

   en.wikipedia.org/wiki/Low-noise_block_downconverter

   The signal received by the LNB is extremely weak and it has to be amplified before downconversion. The low-noise amplifier section of the LNB amplifies this weak signal while adding the minimum possible amount of noise to the signal. The low-noise quality of an LNB is expressed as the noise figure (or sometimes noise temperature). This is the ...

7. Digital active signal collector - Wikipedia

   en.wikipedia.org/wiki/Digital_Active_Signal...

   The amplifier, built into the antenna, receives it power supply via the coax cable between the DVB-T box and the antenna. The advantages of an active antenna compared to a passive antenna and a separate amplifier is that the (low) signal can be amplified before it is subject to loss and/or interference in the cables and connectors between ...

8. Digital Satellite Service - Wikipedia

   en.wikipedia.org/wiki/Digital_Satellite_Service

   Also unlike DVB, all DSS receivers are proprietary DirecTV reception units. DirecTV is now using a modified version of DVB-S2, the latest version of the DVB-S protocol, for HDTV services off the SPACEWAY-1, SPACEWAY-2, DirecTV-10 and DirecTV-11 [2] satellites; however, huge numbers of DSS encoded channels still remain. The ACM modulation scheme ...

   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".
