The satellite antenna is commonly referred to as the "big pot", which is a metal parabolic surface responsible for reflecting satellite signals into the feed source and high-frequency head located at the focal point. The function of satellite antennas is to collect weak signals transmitted by satellites and remove noise as much as possible. Most antennas are usually parabolic in shape, and there are also some multifocal antennas that are composed of a combination of spherical and parabolic surfaces. The satellite signal is reflected by a parabolic antenna and concentrated at its focal point
Classification
Satellite antennas can be divided into two types: forward feed and offset feed.
. Positive feedback is what we often call a big pot, receiving C-band programs Partial feedback, also known as small pot, receives Ku programsFunction of testing report:
