Satellite Dish

A satellite dish is a parabolic antenna used to pick up and send out electromagnetic signals, typically relayed by communication satellites orbiting around the earth. It can be used for data, radio, or television. They come in various sizes and designs. They are also commonly used to receive satellite television.

A satellite captures satellite television signals that reach a viewer's house. A standard dish consists of a bowl-shaped surface and a central feed horn. A feed horn is an antenna used to channel signals between the transceiver and the reflector. It also filters unwanted signals from adjacent channels and other nearby communication satellites by selecting the property of waves to be received.

A transmitting satellite dish sends a signal through the horn while the dish focuses the signal into a narrow beam. A receiving dish , on the other hand, gathers the signal inward and focuses it towards the feed horn and into the controller.

How to Install a Satellite Dish

While a satellite dish can be set up by the local dealer and transported to the site location, the purchaser can also do the installation. This ultimately depends on the size of the dish and the expertise of the purchaser.

The installation site should be 75 metres or 246 feet from the house and must be clear from signal obstructions. Also, consider local building codes and possible microwave interferences from radio or television towers in the vicinity. Clay soil is an excellent ground for installing the base.

The base should be primarily installed. The base is a concrete foundation that extends below the frost line where a concrete base tube is set. The pedestal, where the satellite's elevation arm is connected, is attached to the base tube.

A slab mount installation is considered to be a more stable method than a typical base foundation. It is necessary for unstable sites selected for the installation of satellite dishes. The slab should be 1.6 square feet wide by 3.2 feet deep or 0.5 metres wide by 1 metre deep.

After excavating the soil to a proper depth, the concrete is poured and a triangular steel mount fixture is embedded into the concrete. The pedestal is then attached to the triangular steel mount.

A satellite dish should be cleaned twice a year. This is done by tightening and lubricating its bolts and trimming destructive weeds and trees around it. The alignment should also be adjusted to correct bad reception.
