To pose a parable

Since the arrival of digital television, many satellite dishes have been blooming on the roofs. How to install this very useful equipment yourself, especially in areas not covered by the wireless network?

The choice of location

A satellite dish can be fixed by an anchoring system in one of the walls of the house or a sufficiently solid chimney exit. When properly tightened, this device holds the dish in the chosen position. The choice will be based on the final location of the device relative to the position of the required satellite, while checking that the immediate environment (buildings, vegetation, etc.) does not block the passage of waves.

Fixing and connection

In this case, the dish is fixed to a flue via a flexible tape galvanized steel or stainless steel. The latter surrounds the duct and clamps it in the manner of a tether strap via a tensioner. The coaxial cable connects the demodulator, located in the house, to the dish. It will give much better results if it consists of a single piece, the connections having the defects of reducing the quality of the signal.

Fine adjustments for a crisp image

In order to avoid the use of a satellite pointer, it is possible to directly connect the head of the dish to the demodulator, itself connected to the television receiver (preferably of small size to be able to move and mount it on the roof), and observe for yourself the coming of the image when you change the positioning of the dish. The settings are very precise, it is necessary to move the dish gradually from top to bottom and from right to left, very slowly so as to get the right setting. Once the perfect image is obtained, all that remains is to fix the dish securely in this position, disconnect the demodulator and the receiver, pass the coaxial cable to the place provided for inside the house and reconnect the appliances.

Put the metal strapping around the chimney and tighten the stem securely. It is also possible to use a system of anchoring by sealing in the wall.

Attach the receiver head to the base of the dish using the flat screwdriver. The fixation is obtained thanks to an adjustable collar system coming to wrap around the head.

Attach the PVC board to the dish. Adjust the angle of the dish in the exact direction of the transmitter, using the metal bracket and the flat key.

Then connect the coaxial television cable to the head by sliding the copper wire into the hole provided, then screw permanently.

With the cable connected to the demodulator and the receiver connected, turn the dish to the supposed setting of the local transmitter. When the image appears, lock the dish in this position.

Permanently place the protection around the antenna cable by coming to block it against the receiver head. The seal will be effective thanks to a self-locking seal system.

Secure the cable with outdoor adhesive tape or plastic cable ties. These bindings are intended to protect the cable, avoiding him to move with the wind and bad weather.

In the case of a Roman tile roof like this, you can use tile hooks to run the cable and then close the hooks.

PRACTICAL ADVICE
• If you can not place the receiver
(television) on the roof to check the correct positioning
the sensor, call a friend, a neighbor... who
will guide you as you move the antenna.
• Before any precise adjustment, it is good to know
the orientation of the satellite corresponding to your
demodulator and to your area. A short visit on
Internet will specify the coordinates of this satellite
and will allow you to make the presets more
quickly. An example: the Atlantic Bird 3 satellite
used for this report is at 5° West.
