8.2.1 The outdoor unit
This consists of a receiving antenna feeding directly into a low-noise
amplifier/converter combination. A parabolic reflector is generally used,
with the receiving horn mounted at the focus. A common design is to
have the focus directly in front of the reflector, but for better interfer-
ence rejection, an offset feed may be used as shown.
