The satellite cooker does not need a signal amplifier, it only needs a tuner to modulate and demodulate the satellite signal. The tuner is very close to the signal receiver next to the TV, so the TV signal can be clearly received without a signal amplifier at all.
The satellite antenna is often called the cauldron, which is a metal parabola that is responsible for reflecting the satellite signal into the feed and tuner at the focal point. The function of the satellite dish is to collect the weak signal transmitted by the satellite and remove the noise as much as possible. Most antennas are usually parabolic, and some multi-focal antennas are a combination of spherical and parabolic. The satellite signal is concentrated to its focal point after being reflected by the parabolic dish antenna.
