Used at the focal point of a satelite antenna (dish) to amplifiy the received signals.
A device that receives and amplifies the week satellite signal reflected by a dish via a feed.
An amplifier with low noise figure that is typically used at the front end of a radio receiver.
This is the preamplifier between the antenna and the earth station receiver. For maximum effectiveness, it must be located as near the antenna as possible, and is usually attached directly to the antenna receive port. The LNA is especially designed to contribute the least amount of thermal noise to the received signal.
A low noise signal booster used to amplify the weak signals received on a satellite antenna. Usually found in the receiver front ends.
