how to setup a satellite dish (part1) - Technology - Electronics

Setup a Satellite Dish

A 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.
