Receiving Equipment 1

Introduction • This section discusses the variety of equipment and hardware the customer will need in order to receive the DIRECTV programming from the satellites 2

Objectives • List the equipment and hardware needed to receive DIRECTV programming • Explain how the LNB operates • Explain how the receiver selects programming • List three functions of the access card • Identify the correct ODU/LNB configuration 3

Receiving Equipment IRD- Integrated Receiver, Decoder LNB Low Noise Block, Down Converter ODUOut Door Unit Access Card 4

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 5

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 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? 7

Receiving Equipment • ODU and LNB – Single Satellite ODU 8

Receiving Equipment • Multi. Switches 3 X 4 6 X 8 4 X 8 9

Basic System Overview (Multiswitch) • What is a multiswitch? – Standard 3 X 4 – Standard 4 X 4, 4 X 8 – High Frequency wide band 6 X 8 or 6 X 16 10

Basic System Overview (Multiswitch) • How does a basic multiswitch work? NOTE: Older multiswitches may have 17 volts listed for LHCP. 11

Diplexer • Diplexers are used to insert off air channels on the same cable as the satellite channels. 12
