1. Classification of Satellite Antenna
Center focused satellite antenna
The center focus satellite antenna commonly refers to the positive focus antenna satellite
antenna, also known as parabolic antenna, regardless of the depth. The surface of satellite
uhf yagi antenna curvature was highly parabola. The characteristic of the center-focus
antenna is the disk perfect circle, and the LNB (LNB) is placed in the central focus of
antenna. According to their focus position, coke antenna can be divided into a deep plate
with a shallow dish, and each antenna has its own advantages and disadvantages. When the
positive focus antenna finds the satellite, usually know the local reception of the satellite
elevation angle, put the Yang degree at the antenna center to adjust the elevation angle, and
you can easily find the satellite you want, and then with a compass and satellite signal test
instrument. When the positioning is completed, then the central disk, LNB (LNB) and 30,006
thousand kilometers satellite are in a straight line.
The FRP unibody satellite antenna
FRP antenna is made of glass fiber. The foil is fixed in the fiber to be used home folder as a
reflection of satellite signals. Production process is usually used in the mold bulky antenna to
produce by hand. Due to this antenna is one piece, then it can guarantee absolute roundness
and the accuracy of the parabolic surface and completely avoid the trouble of "side lobes" or
"multifocal" caused by the improper combination of antenna. The antenna is especially
suitable for the KU-band satellite receiver for its accuracy is higher than the combo antenna.
The features of unibody antenna is that it has the high gain with the uniform quality of wifi
antenna gain, different from the combination antenna gain quality depending on the mood of
the engineering construction. The disadvantage: there is a certain degree of difficulty in
transportation and high-rise operations. FRP antenna can be used to receive the C and Ku-
band satellite signal. General use in cable television systems, TVRO satellite communication
systems related to manufacturing. Due to this type of antenna is subject to the accuracy of
the antenna curvature, it is more often used in the low-frequency C-band satellite receiver.
Molding and iron plate antenna

2. Iron plate antenna is one of the highest utilization rate in the individual receives. It can be
divided into partial coke forming one, the central focus of one piece and multi-piece
combination central focus. Generally it is available to receive Ku-band satellite. The one
piece antenna is cheap to install signal gain stability. The only drawback is that it is more
inconvenient to handle for more than 100cm. Iron plate antenna is formed using galvanized
steel sheet plus stamping. It can be mass-produced. Therefore, the price is cheaper.
