SR2014 Satellite Receiver (160-2511) Installation Faxback Doc. # 31858 The Radio Shack C-Band Dual-LNB is intended for use as an upgrade for standard Radio Shack Home Satellite Television (HSTV) systems. You can also use it to upgrade some other single-LNB satellite systems. When you use a C-Band Dual-LNB Feedhorn with a satellite system that has more than one receiver, the number of satellite channels available for independent selection by each receiver doubles from 12 to 24. You also need the following accessories when you install the dual-LNB feedhorn: Dual-LNB Switches (Cat. No. 15-2001)-one for each satellite receiver in your system. Two Coaxial Cables Between the Dish and House-a second coaxial cable is provided in Radio Shack's standard satellite system cable. An Additional C-Band LNB-for the earlier Radio Shack HSTV receiver (Cat. No. 16-2501),you need an LNB that converts the satellite signals to the 430-930MHz range. For the new Radio Shack HSTV receiver (Cat. No. 16-2507) you need an LBN that converts the signals to the 950-1450 Mhz range.Both types of LNBs are available by special order from your local Radio Shack store. 75-Ohm Hybrid Splitter(Cat. No. 15-1141C) NOTES: You can use a dual-LNB feedhorn in a satellite system with only one receiver. This eliminates mechanical polarity switching at the LNB and provides more flexibility of operation if you add more receivers later. This sheet provides only the instructions for installation of the dual-LNB feedhorn. Connections of the LNBs to the dual-LNB switches and the satellite receivers should be covered in the manuals for those products. ATTACHING THE LNBS TO THE FEEDHORN Attach one LNB to each of the feedhorns rectangular openings. This procedure is similar to the one outlined in your satellite system manual, except you do not use a right-angle wave guide with either LNB. ATTACHING THE FEEDHORN TO THE DISH The feedhorn has several sets of holes for mounting it on different satellite dishes. ATTACHING THE COAXIAL CABLES At the dish, attach one coaxial cable to each of the LNBs. When you make the connections to your satellite receiver (or dual-LNB switches) you need to know which cable is connected to the vertical LNB and which one is connected to the horizontal LNB. With Radio Shack satellite systems cables you can identify the different coaxial cables by their positions within the complete satellite cable assembly. (/all-04/12/96)
