Receiving Equipment
• What is an LNB?
– LNB stands for Low Noise Block. It receives
microwaves signals from the satellite,
amplifies them and converts the signal to a
lower frequency band

Basic System Overview
(ODU)
• What is an LNB?
– Low Noise Block Converter
• What is Polarization and how many
polarities are there?
– 2 Circular polarities per orbital slot
• Right Hand Circular
• Left Hand Circular
6
Basic System Overview
• Review:
– What are the three basic components of a
satellite system?
– What is an LNB?
– What does it do?
– How is an LNB powered?
– What is polarity?
– How does an LNB switch polarities?

Diplexer
• Diplexers are used
to insert off air
channels on the
same cable as the
satellite channels.
