Overview

Warnings

The installation, operation, and maintenance of the 3.7-Meter Earth Station Antenna requires qualified and experienced personnel. Andrew installation, operation, and main- tenance instructions are illustrated for such personnel. Additionally, the antenna should be inspected by qualified personnel to verify proper installation, maintenance, and con- dition of equipment as described in Preventive Maintenance. The basic equipment and accessories are either manufactured or design controlled by Andrew Corporation.

The prerequisite information necessary for the 3.7-Meter Earth Station Antenna can be found in this section. Furthermore, this section should be reviewed BEFORE performing the installation, operation, or maintenance. Warnings, recommended tools, and the antenna parts can be verified and/or determined with such a review.

When installing the 3.7-Meter Earth Station Antenna, be conscious of the warnings pre- sented below. For further information or clarification of this information, contact the Customer Service Center. The warnings are as follows:

1.Electrical shock from voltages used in this antenna system may cause personal injury or death. Prior to making any electrical connections or performing maintenance or repair, ensure that the power is removed. Electrical connections should be made only by qualified personnel in accordance with local regulations.

2.Installation of antennas may require persons to work at elevated work stations. Whenever persons are working at eight or more feet above the ground and not on a guarded platform, they should wear safety belts with at least one (preferably two) lan- yards.

3.Never stand underneath any object while it is being lifted.

4.Always wear a hard hat, especially if someone is above you.

5.Make sure no person is in or under the reflector while it is being lifted or positioned; personal injury can result if the reflector assembly falls.

6.Personnel should never be hoisted in or out of the reflector by the crane; personal injury may result.

7.Andrew earth station antennas supplied to standard product specifications will survive

125mph winds in any operational position in moderate coastal/industrial areas. Severe conditions require additional protection. Should it be expected that winds will exceed

125mph, it is recommended that Andrew antennas be steered to specific azimuth and elevation orientations to minimize wind forces upon the structure and thereby increase the probability of survival.

8.It is recommended that all cross-axis waveguide and coaxial cables are secure such that high winds will not cause excessive flexing. Position the antenna to an elevation of

90degrees. The azimuth jackscrew should be placed in the center of its travel.

9.When the antenna is transmitting, severe eye injury or injury to other parts of the body can result from exposure to radio frequency (RF) energy. The antenna must be turned off before entering the area in front of the reflector and near the feed.
