What is an active antenna and passive antenna?

Thanks to the dynamic development of television broadcasting in the modern world, there is probably no person who does not encounter antennas. In order to watch their favorite TV shows in the best quality, the user needs to connect the antenna to his receiving equipment. And then the question arises: which antenna to choose, active or passive? In this article, we will consider in detail the features of each antenna, as well as the scope of their application. But first of all, it is necessary to give a detailed definition of the very term “antenna” and briefly describe the history of creation.

Heinrich HerzAntenna is a special device whose main task is to receive or emit radio waves. It converts the fluctuations of the electric current into a radio wave or vice versa. As can be seen from the definition, antennas can operate on reception, transmission, or transmission. The simplest antenna operation Continue reading

Famous Brand Satellite Television Equipment

Satellite TV is a high-tech service that offers the user a huge selection of television channels for every taste anywhere in the world. Satellite dishes mounted on the walls and roofs of houses have long been accompanying our lives, allowing you to watch satellite television at home. A dish connected to the receiver is installed stationary, is oriented to the satellite and works in one position for the entire service life.

Another thing is satellite TV equipment for mobile objects, for example, cars, buses, trains or ships. On a moving object, which is any vehicle, installing a satellite dish is useless, because without an accurate orientation to the satellite, the entire system is unsuitable for use and will be like a stopped clock showing the correct time only twice a day.

Types of Satellite Antennas

Satellite antennas are made as solid / all-stamped, mesh and precast / sectional. The solid ones are made of a whole metal sheet and have a shape without technical holes and joints. Their signal reception quality is better than the others, and the design is less prone to kinks and defects during operation.

Mesh antennas are assembled from strips, forming a receiving grid. Their advantage is less windage, so mesh satellite dishes are preferred in areas with increased wind load.

Prefabricated antennas are made of petals and can be compactly packed for transportation and long-term storage. They, like sectional ones, are convenient for regular transfer, as they are easy to fold and allow you to quickly deploy the system. Cons of the design – in the weak joints of the petals, which are easily broken and require regular professional maintenance.

Mesh satellite dishes have slightly worse signal quality than all-metal antennas, but not due to technical holes. Since for the correct reflection of the beam the shape of the mirror must be strictly parabolic, it is Continue reading
