A sensitive preamplifier mounted on the rear of the feed assembly between a satellite terminal's antenna and receiver.
Notes :
For maximum effectiveness, it must be located as close to the antenna as possible and is usually attached directly to the antenna receiver port.
It is designed to contribute the least amount of thermal noise (usually rated in equivalent noise temperature) to the received signal. The lower the temperature, the lower the noise.Termes :
- low noise amplifier
