4. INSTALLATION

Site selection and general installation guidelines are provided in this

section, including instructions for cabling, antenna and power source

connections. Power up procedures, initialization and functional test

procedures are described that should be performed prior to placing the

MCC-545C on-line within the network.

4.1 Site Selection

There are 5 important factors to consider in selecting an optimum site:

1. External noise/interference

2. DC power source

3. Horizon angle

4. Antenna type

5. Antenna height

4.1.1 External Noise/Interference

Noise and signal interference can reduce the performance of the MCC-

545C. The most common sources of noise and interference are as

follows:

• Cosmic Noise

• Power Line Noise

• Automobile Ignition Noise

• Computer-Generated Interference

• External Signal Interference
