User Manual Dual C or Quad Ku Band TVRO Antenna (9497B-21)

Basic System Information9497B-21 C/Ku-Band TVRO3.3.3. Above Decks AC Power SupplyPedestal Power - An appropriate source of AC Voltage (110 VAC 60 Hz OR 220 VAC 50 Hz) is required forthe above decks equipment. Refer to the Specifications section of this manual for the power consumption ofthe antenna pedestal.3.3.4. Satellite ReceiversThe TVRO Antenna system, with the appropriate LNB installed, can be used with standard European satellitereceivers, and Integrated Receiver-Decoders (IRD). Both can receive “free” programming, but an IRD isrequired when the desired programming is encrypted. When authorized, it will decode the encrypted signalsfor use. Authorizing the receiver-decoder is a process of registering your receiver(s) and paying subscriptionfees to the service provider. The service provider then arranges for a signal to be sent through the satellite toyour receiver-decoder, which will “enable” it to decode the programming you subscribed to.A coax connection from the antenna (via the matrix switch) provides signal input to the receiver. Thereceiver also outputs voltage and tone control to the matrix switch to select the correct band andpolarization signal for the channel you want to watch. A coax connection from the TV OUTPUT jack on thesatellite receiver is connected to the ANTENNA INPUT on the television. Alternately, individual audio/video,Audio & S-Video, or SCART cable connections may be made between the satellite receiver and the television.3.3.5. Television/MonitorAn appropriate television monitor is used to view the satellite television programming and to view the onscreen displays from the receiver.3.3.6. Matrix SwitchA matrix switch must be installed with all of the antenna IF coax cables connected to its’ LNB inputs. A coaxcable (RG-6 OR greater) is connected from each matrix switch output to each satellite receiver. Sea Telrecommends that an ACTIVE Matrix be used in all installations. Matrix switches with 4, 8, 12 and 16 outputsare available.Each of the outputs can be connected to a satellite receiver, one of these outputs must be connected thetracking receiver in the ACU. Each output of the matrix switch is controlled by voltage, and/or tone, from thesatellite connected to that output connector. This voltage, and/or tone, selects which of the input signalsgets routed to that output connector, therefore, to that receiver. Each output of the matrix switch operatesindependently of the others, therefore, allows the satellite receivers to operate independently also. As youchange channels on the satellite receiver, it uses the voltage, and/or tone, to select the correct signal input forthe channel you have selected.3-6
