Dish Antenna:

It is a receiver antenna that receives the signals propagated by the satellite and provide to the T.V. Receiver.

Process for the Installation of Antenna:

I. Choosing the proper place: First we should select the correct place for installation.

1.    It have to be an open place. Objects such as trees, hills, buildings should be avoided since the signals will be weak.

2.    It should be visible and have to be fixed in the direction of the satellite.

3.    The place selected, have to be 20 feet along the power line.

4.    It can be installed on a terrace, upstairs, out walls or pillar.

II. Ground

A good grounded minimise the bad reactions.

1.  The bad influences from, lightning and thunder affects the receiver. It may be shocked while operation, even death will also be happen. Thus it must be grounded properly.

2.  We can make the ground along with parallel to EB ground. Otherwise we can ground separately through using pipes.

III. Assembling of Antenna

1.  The antenna have be fixed very strong, even should not disturbed through any natural calamities like storm, rain etc.

2.  We can make use of the RG6 cable wires to connect the TV and the antenna.

3.  The cable has to be 25m length.

4.  We can receive the transmission line via walls or ground.

IV. Fixing and testing of antenna

1. First select the direction of the satellite and then fix the stand of dish antenna. After fixing, the antenna stability and strength have to be tested.

2. Angle (AZ-EL) of the dish antenna must be checked and then it must be fixed with

Screws and bolts. [AZ side angle left to right, EL-up and down angle].

3. Then fix LNB with V shape bolt-nut at the opposite side of the dish.

4. Cable wire must be connected among T.V and antenna.
