FIGURE 7 FIGURE 8 12. Attach the rectangular feed tube to the antenna socket. Make certain the large round hole for the spacer is positioned as shown in Figure 7. Tighten bolt while holding nut. 13. Attach the LNB Adapter to the feed tube with #8 hex insert nut and 1" long Phillips head screw. See Figure 7. Do not overtighten to the point of deforming the feed tube and the LNB Adapter. 14. Install plastic Cover Clip in the Plastic LNB Adapter in the empty space between Sat A and Sat B dual LNBs before mounting LNBs. See Figure 8. 15. Before making any wire connections, read "Connections", Page 18. The next steps involve making the coaxial cable interconnections between the LNBs, multiswitch and the satellite receivers. First, choose one of the mounting location options for the multiswitch listed below that best fits your installation. Use approved installation kits with high quality, low loss RG6 coaxial cable to insure the best performance under all conditions. All coaxial cables must be grounded outside at the point of entry. Contact a licensed inspector or electrician in your area for assistance. General grounding requirements are outlined in Figures 11 and 12. MULTISWITCH LOCATION OPTIONS: • Option #1: Mounting a weatherproof multiswitch to the back of the antenna as shown in Figure 9. This location is simplest for installations that use one receiver since only one cable enters the building. If this option is selected, connect the LNBs to the multiswitch per the following instructions while on the ground with coaxial cables. Depending on your model, a 4-cable set may be included for ease of installation. • Option #2: Mounting the multiswitch inside the house. This option provides the best weather protection and may provide the easiest access for future wiring changes, such as adding additional satellite receivers. • Option #3: Mounting the weatherproof multiswitch under the building eaves at the point of cable entry. This option provides excellent weather protection to the wire connections and the switch. It eliminates the coaxial ground blocks since the multiswitch also serves as a grounding block for the four LNB cables connected to it. NOTE FOR OPTIONS #1 and #3: Typically in a single family home, the RG6 cable for the supplied 4 x 4 mulitswitch does not exceed 100 feet from the satellite receiver(s) to the LNBs. For installations where each RG6 cable run from the satellite receiver(s) to the LNBs exceeds 100 feet, such as often encountered in a commercial or multi-dwelling building, it is recommended that you use an AC-powered multiswitch (not supplied). An AC-powered multiswitch powers the multiswitch and the LNBs directly from an AC/DC power module so that the satellite receiver is capable of driving a longer RG6 cable. Contact Channel Master Technical Service for an Application Note concerning such installations. Other manufacturers may offer similar products. 16. Even though all the above mutiswitch location options are used by installers, this manual will concentrate on option #1. If an installer chooses to install the multiswitch in the house or at the point of entry to the house, then cables of proper lengths must be cut. To prevent corrosion, weatherproof outdoor connectors with rubber o-rings must be used for all outdoor connections. See Figures 11 and 12 for general wiring diagrams. -11-
