[. . . ] Panasonic Installation Manual TA-DA2420 for DIRECTV PLUS TM Satellite Dish Antenna or DIRECTV PARA TODOS TM Satellite Dish Antenna INTRODUCTION This antenna system, with the equipment supplied, can receive signals simultaneously from satellites located at 101° and 119° West longitude orbital locations. This antenna system also has a reserved position for a satellite located at 110°W for additional services. If such services are offered in your local area, you will be notified. The installation procedures listed in this manual require basic knowledge in construction, assembly and wiring. [. . . ] 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- ON-GROUND INSTALLATION WITH MULTISWITCH ON BACK OF DISH - OPTION #1 1. To install the outdoor multiswitch to the back of the antenna, use the #8 self tapping screws and washers provided in the multiswitch carton. CAUTION: Use a hand tool to tighten the screws until the face of the screw head is evenly touching the multiswitch mounting lug ­ then tighten ¹/ turn more. You will also need 4 cables to make the connections between the multiswitch and the LNBs. A set of gray cables is provided for Option #1, in most antenna models. The cables are routed from the multiswitch through the feed tube to the LNBs as shown in Figure 10. The cables should be dressed as shown using the cable clips provided in the hardware bag. IRD cables should be routed underneath the gray cable set as illustrated in Figure 9 (one IRD cable shown in black). With the exception of the IRD cable, it may be easier to perform much of this installation on the ground. FIGURE 9 -12- 2. Review Figure 10 for multiswitch wiring. Multiswitch Installations Using Sat A & Sat B (Two Dual LNBs) FIGURE 10 3. Pass one end of two coaxial cables (labeled "Sat A" on both ends) through the rectangular feed tube on the side marked "Sat A". Then attach them to the LNB that will be mounted in the position marked "Sat A" at the end of plastic LNB Adapter. If labeled cables are not supplied, then mark two cables on both ends "Sat A" with masking tape. Repeat Step 3 for inserting the two coaxial cables (labeled "Sat B" on both ends) in the other side of the feed tube and connect to the second LNB that will be mounted in position marked "Sat B". Tighten all cable connectors on both LNBs. Carefully push the LNBs and attached cables into the LNB Adapter all the way flush with the edge of the LNB Adapter and secure with #8 insert nut and 1" long #8 phillips head screw and then tighten screws. Slight movement of LNBs after tightening is normal. Connect opposite loose end of the cables labeled "Sat A" from "Sat A" LNB to the multiswitch "Sat A" terminals as shown in Figure 10. [. . . ] Once the signal is acquired, the Elevation Adjustment setting may need to be fine tuned to maximize the signals. The most critical procedure is the proper plumbing of the dish antenna mast. It must be plumb and level, otherwise the acquiring of both satellites is difficult and even if the satellites are acquired, it may not be an optimum setting and is therefore prone to rain, snow, wind outages. When using a compass to set initial "azimuth" as indicated by the receiver's dish-pointing menu, make sure the compass is not falsely deflected by any nearby metal object(s). [. . . ]
