Some general guidelines for Mounting brackets The plastic Y-Yoke can use both the Dish and DirecTV lnb's (D-shape and rectangular fitting). It is the only mount that can accommodate Dish/ExpressVU lnb's. It is required for mounting the twin and quad lnb's. There is nothing to adjust. It works best on dishes that can be skewed to align each lnb to the correct elevation. The metal bracket for 110-119 or 82-91 is very easy bracket to set up. If your dish is already set up for one of the satellites, add the bracket to the existing lnb. If the dish is pointed at 110, make sure the dish lnb is on the side of the bracket marked 110. Just add the other lnb in the bracket and it will be aligned to 119. You can adjust the lnb within the bracket to tweak the signal. The MagicMount and SuperMount brackets replace the existing lnb holder on the dish. Attach the bracket so that the center lnb is in the same postion that it would have been in with the original lnb holder. It is important to keep the centre lnb at the focal point of the dish. It may help to use the original lnb holder first and measure the vertical distance between the top of the lnb and the dish arm and the horizontal distance from the lnb to the dish. The MagicMount or Super Mount may attach to the dish arm from the top or bottom, whichever puts the center lnb at the focal point of the dish. With the bracket mounted, align the dish so that the center lnb receives signals from the satellite with the weakest signals first. Generally, circular signals (Bell, Dish, DirecTV) are much easier to receive than linear signals (T5, AMC4). The focal point of the dish will provide the strongest signal possible. When setting up a dish to receive signals from satellites with linear and circular signals, you may want to get a refence point for your dish first, by using a circular lnb in the centre positon and finding a strong satellite (Bell/Dish) with the centre lnb first. Once the elvation and position of the dish are set, replace the circular lnb with a linear lnb and slightly move the dish until you get the linear signal you want on the centre lnb. Lock down the dish once the centre lnb is providing the best signal possible. Add lnb's to the side for the other satellites. When lnbs are touching they are able to receive satellites that are about 8 degrees apart. If the satellites you want are closer, you will have to turn the outer lnb slightly towards the center. With the MagicMount, you can actually place 1 lnb behind another so that they overlap to get within a couple degrees of each other. You can adjust the lnb to the elevation of the satellites either by skewing the dish OR adjusting the height of the lnb. When adjusting the position of the lnb remember that you have a mirror effect because you are adjusting the lnb to the reflected signal not the satellite itself. ie if the outer satellite is lower in the sky than the center satellite, the lnb must be higher than the center lnb to get the signal. If the outer satellite is to the right of the center satellite, the lnb has to be to the left of the center lnb. It is best to align all the lnbs before installing switches. There is some loss of signal for every switch you use.
