2.10 Site Installation
The installation of the DATA-20 involves several considerations. A proper installation is usually
preceded by a pre-installation site survey of the facilities. The purpose of this survey is to
familiarize the customer with the basic requirements needed for the installation to go smoothly.
The following are some considerations to be addressed (refer to Figure 2-8 for Site Installation
Details).
Before taking the product to the installation site verify that the interface connections are
compatible with the equipment to be connected. Also, locate the information provided by the path
analysis that should have been performed before ordering the equipment. At the installation site,
particular care should be taken in locating the product in an area where it is protected from the
weather and as close to the antenna as possible. Locate the power source and verify that it is
suitable for proper installation.
The installations should only be performed by qualified technical personnel
only.
