What is the Satellite Communication Antenna?
The role of satellite antennas is to collect weak signals from satellites and remove noise as much as possible. Most antennas are usually parabolic, and some multi -focus antennas are composed of spherical and parabolic surfaces. The satellite signal is concentrated in its focus through the reflection of the parabolic antenna.
What is a microwave communication system?
A communication system composed of microwave sending machines, receiving machines, heavenly feedback systems, multi -way reuse equipment and user terminal equipment. Microwave communication system, using microwave communication has a large capacity, good quality, and can be passed to a long distance. Therefore, it is an important communication method for the National Communications Network, which is …
Interference and measures of satellite TV receiving signals
Satellite TV receiving systems mainly include antenna, feedback, high -frequency head, and satellite receiver. The parabola satellite antenna receives the feed signal focused on the front end of the satellite high frequency head, and converted to the C frequency (3.7GHz ~ 4.2GHz) signal or KU frequency band (11.7 ~ 12.75GHz) signal. out. Digital TV signals …

Why is the TV launching antenna so high?
The images and sounds received by the TV are transmitted by radio waves. During the spread of radio waves, the TV receiving signal is weak if it is blocked by tall objects. In order to prevent tall objects from blocking the radio waves, the TV launch antenna is generally more outdoors. Pay attention to lightning …
The principle of car antenna?
The car antenna is also called the car antenna. Generally, the antenna on the car is used for the radio and radio on the car. It can be divided into the built-in antenna and the external antenna of the car. However, there are other antennas installed in the car according to different purposes. If the …
What is the microwave antenna?
Microwave antenna of Contents Microwave antenna Transmitting or receiving antennas working in meter wave, centimeter wave, millimeter wave and other bands are collectively referred to as microwave antennas. Microwaves are mainly propagated by space waves. In order to increase the communication distance, the antenna is erected higher. Among microwave antennas, parabolic antennas, horn parabolic antennas, …
what’s the antenna?

How to install a satellite dish?
When installing the parabolic antenna, it is generally installed according to the structure diagram provided by the manufacturer. The antenna structures of various manufacturers are basically the same. The structure of the antenna reflector has two types: integral forming and splitting (the reflector above 2M is basically splitting). The tripod mainly includes pole mount tripod …
What should I do if the TV cannot find WiFi?
TV cannot find wifi of Contents The distance between the TV and the router The distance between the TV and the router is too far, so that the TV cannot receive the wifi signal. Generally, moving the router closer to the TV can solve the problem. The SSID broadcast of the router is turned off …
