A DIRECTV satellite dish is designed to receive transmission from an overhead satellite that can be turned into video that a television set can display. By the installation of three LNB modules (low noise amplifier block) on the dish, the DIRECTV satellite receiver can use two tuners to enable the view to watch one program while recording a second simultaneously. The set-up is straightforward, if involved, and requires a DIRECTV satellite kit and tools that most homes already have on hand.

Instructions

  1. 1

    Stand on the roof, facing south--a compass will help with this. Place the DIRECTV satellite bracket on the roof. Secure the bracket to the roof with wood screws using a Phillips screwdriver. Cover the screws with silicone sealant to protect the roof from the elements.

  2. 2

    Screw the back of the satellite dish to the bracket using the Phillips screwdriver. Loosen the knobs on the side of the bracket with your fingers. Rotate the dish so that the front is facing south. Tighten the knobs back down with your fingers.

  3. 3

    Place the bracket that is at one end of the lateral transmission support pole against the bottom front of the dish. Line up the screw holes on the bracket with the dish. Screw the screws into the bracket with the Phillips screwdriver.

  4. 4

    Place the triple LNB module on the far end of the pole. Rotate the module so that the plastic-tipped end faces toward the dish. Tighten the screws on the side of the module.

  5. 5

    Screw an end of a 3-foot coaxial cable into each of the coax outputs on the bottom of the triple LNB module. Screw the free ends of the coaxial cables into the first three coax inputs on the satellite multi-switch. Secure the switch to the side of the dish with a plastic twist tie.

  6. 6

    Screw an end of the 100 coaxial cable into the first coax output on the switch. Run the cable along the roof, over the edge and into a window on the floor where you will be watching TV. Drill a hole in the side of the window with the portable drill. Pull the end of the coaxial cable through the hole. Secure both sides of the hole with silicone paste.

  7. 7

    Run the coaxial cable along the baseboard of the wall until you reach the satellite receiver. Screw the free end into the coax input on the coax adaptor. Screw a free end of each of the 1-foot coaxial cables into the two coax outputs on the coax adaptor. Screw the free end of the two coaxial cables into the two coax inputs on the back of the receiver.

  8. 8

    Connect an HDMI cable between the HDMI output on the receiver and an HDMI input on the TV. Turn the TV on with its remote. Press "Menu." Select the HDMI input the cable is plugged into from the "Video input" setting. Press "Menu" to exit the settings.

  9. 9

    Turn the receiver on with its remote. Press "Menu." Go to the "Setup" menu and select the "Dish coordinates" option. Enter your zip code in the text field on the screen. Press the "OK" button. Write down the "elevation" and "azimuth" numbers for your location that are now listed on the screen.

  10. 10

    Return to the satellite dish. Loosen the knobs on both sides of the bracket with your fingers. Raise and lower the dish slowly so that the "elevation" marking on its side lines up with the scale at the number that must be set. Tighten the knob with your fingers so that the dish can no longer be raised once the number is set. Repeat this procedure, only moving the dish from side to side until the number for the "azimuth" setting is reached. Tighten the knob with your fingers.

  11. 11

    Angle the dish so that the dot on its back lines up with the setting on the scale that matches the number provided in the DIRECTV instruction manual for the dish--this information can also be procured on the "Support" page of the DIRECTV's website.

Tips and warnings

  • You must have a DIRECTV service subscription or the satellite receiver will not accept any signals from the satellite dish.
