Satellite Receivers


As it is already known, satellite technology is rampant in the contemporary world. While this is true, without the instruments to propagate it, it will all be useless. Therefore, all the technical knowledge of man has culminated to the invention and innovation of satellite receivers. Now a common gadget amongst the masses, its different uses allows it to be a potential mainstay in our lives here in the digital age. Remember that these devices were made to push forth the evolution of telecommunications technology.

Satellite receivers are basically dishes that you install to connect to the satellite service of your choice, whatever its functionality may be. Also installed would be a decoder to translate the information into something that the receiving machine can understand. For example, if it is a satellite television service, there would be a satellite receiver connected to a set top box, which would be connected to the television. The satellite receiver catches the TV signals and is decoded by the set top box so that the television can show it.

Satellite Receivers

A satellite dish is basically this parabolic piece of material fitted with what is called a feedhorn, which is basically that stick-like thing protruding from the said dish, which can pick up microwave signals that emanates along the air from the source. The signal has a certain signature which makes it distinguishable for the receiving dish, whose programming dictates that it can receive such signals. With this basic functionality, it can receive any form of information carried by the signals as long as it is within range and is programmed to do so.

Theoretically, anything can be made to actually receive signals to a certain extent. But the shape that we all know of, which is that distinct dish shape, has been found as the best shape to receive those signals. With that wide parabolic shape, it "catches" those signals like how a big net can catch schools of fish. Because of that, application of this technology was made much simpler than anyone would have imagined during its days of conception.

There is common misconception that the feedhorn is the thing that receives the signals. This may be true, but the signals do not go to it directly. Instead, the dish's purpose is fulfilled by catching the signals and due to its parabolic shape, can bounce them onto the feedhorn itself. The funny shape is not there without any logical reason. The dish of the satellite receiver was an ingenious solution to the problem of signal reception. With that particular shape, the satellite can receive more signals than a conventional antenna, thus fulfilling its purpose with a higher rate of efficiency.

Satellite receivers are classified as reflector antennas, and any material that reflects radio waves can be used to create the dish. They can range from trash can lids, curved pieces of plastic, to the conventional satellite receiver available in the market. This variety of sources makes satellite receivers possible to be made by anyone with enough knowledge in electronics and communications. This scenario does seem like something out of a science fiction novel, but it is possible and very handy to know about.

The disadvantage, though, is almost like that of a conventional antenna. Things such as raid fade, grounding, birds perching on it, thunderstorms, and maybe even the occasional solar flare can cause interruptions with the feed. It is crucial that the satellite receiver be placed at a strategic location where the possibility of interruptions is at its lowest. There are motorized satellite receivers available for this purpose, which can turn 360 degrees, although they can be more expensive than conventional ones.

The important point is to care for the satellite receivers and make sure that they are hooked up right to ensure its long service life. Technology can get you far to a certain extent, but if you do not care for it, then you may break it.
