Setup a Satellite DishA satellite dish provides you a better reception of picture and sound and wider variaty of local and foreign channels.
Before you begin:
A) What you need to know:Your antenna consists of two parts: the dish that must be pointed to the satellite and the LNB that will get the signals from the dish and send to a demodulator. It is positioned by an arm designed for this purpose.
Coaxial cable:This cable will carry signals from the LNB to the receiver. To preserve the quality of these signals and prohibit any interference outside, it is desirable that this cable is shielded and specific to the dish. Evaluate widely cable length needed to connect the head to the receiver taking into consideration all the obstacles to overcome. It is advised to be generous to avoid surprises as any addition of extension can alter the signal significantly. In order not to cause loss of signal, coaxial cable must not exceed 50 meters otherwise you have to provide an amplifier. Two F plugs will allow the connection of the cable to the head and the receiver.
The demodulator:The receiver will receive, through the coaxial cable, signals from the LNB. These signals are mixed, it will sort them and assign them to channel preset at the factory (see manufacturer's instructions).
The scart lead:This cord will connect your receiver to your TV and send the selected signal.
The TV:The TV will receive the signal from the receiver and turn it into image and sound. Some channels from the satellites broadcast images of 16:9 and stereo sound. To see and hear these programs like that are issued, your TV must be a model for this purpose.
The Dish:The dish should be strictly be directed to the wished satellite direction. The satellites are in orbit 36,000 km above the earth. The setting of a dish is fixed. In fact, the satellites are in geostationary orbits says that is to say that their position relative to the ground does not change regardless of time or season. Your antenna should be pointed at the satellite you have chosen. (See manufacturer's instructions). A new setting will be necessary if you choose a different satellite. It should not be obstacles between the dish and the satellite. In general, the sky must be reached between 60 and 80 degrees to the horizon. If you install your antenna in the winter, remember that the trees will later hide the signals. If there is an obstacle in the shaft must be 1.5 times the height of the barrier down to avoid being embarrassed.
B) Preparation:Assemble your dish in strict accordance with the installation instructions. You need then to mount the fixing bracket vertically. So you need to find a wall that will allow you to fix the dish, and move it sufficiently from side to side. Because the dish provides an important wind resistance, the fixing system must be firmly anchored in the ground or into a wall.
Installation:The installation of the fixing bracket:
- make a hole with the drill,
- put the dowels,
- put the fixing bracket,
- set screws,
- keep it strictly vertical.
In the presence of a classical wall, use a hammer drill equipped with concrete forest. And ankles are placed and the mast is securely fastened.
The installation of the dish:The dish is then placed on the bracket loosely so as to rotate at least 20 ° on both sides.
The adjustment of the elevation:You need now to find satellites direction to point your dish. Use out tool as a satellite finder for that
- Define the degree of elevation depending on your location and the chosen satellite.
- Report the degree of the scale on the side of the dish.
- Tighten the nut.
- Use satellite finder to find the satellite's direction and point the dish to it.
- Tighten the mounting without the block because the antenna will still rotate when the head precisely to the selected satellite.
The coaxial cable:
- This requires a pre-mounted sheet F at the end of your cable.
- Strip the cable of 13 mm without touching the braid that falls under the sheath.
- Delete the visible part of the copper foil shielded cables.
- Fold the braid back and wrap it around the cable sheath. The inner cable that appears consists of a new sheath surrounding a copper wire. Strip the inner cable to expose the copper wire.
- Insert the plug into the cable through the side opposite the nut.
- Visser. The braid must be taken between the sheath and the stem of the plug.
- Pushing the body of the plug the son of the braid that could still pass. The braid must never touch the copper wire.
- Connect the coaxial cable to the LNB by tightening the plug without excess. The installation of this card is extremely important because it affects the operation of any facility and largely determines the quality of the image.
Adjusting the antenna:
- You now need to settle your antenna. If you are not for the TV screen, use a small portable receiver and place your receiver as close to the antenna. It is also possible to use a controller field.
- Connect your TV and your receiver to the mains. Do not switch on until you run the connections.
- Connect your receiver to your TV using the scart lead.
- Install a new card F at the other end of the coaxial cable and connect to your receiver.
- Turn on your TV and your receiver. Channels of your receiver is preset at the factory. You just have to position it on a channel that corresponds to one of the channels broadcast by the satellite you have chosen. You will find these channels in the user manual of your receiver. No specific adjustment is to be performed at the TV.
Finish:It is advisable to protect the coaxial cable and the LNB with sealing caps.
- Connect the coaxial cable to the mast of the dish by keeping it flexible hose.
- To follow the planned route the cable to your receiver located closer to your user.
- Use jumpers or more of the glue. The use of staples is not recommended as they can by cutting the cable or by crushing it and even alter the signal cut.
- For the same reasons never to bend the cable at right angles to make but it curves. When the cable passes from outside to inside along a downward slope it must form a small loop so that water does not penetrate inside.
- Never block the air vents of your receiver. Avoid them large temperature variations and dust. Never place anything heavy on it and not allow water that can be reversed in the vicinity.
