Overview
Warnings
The installation, operation, and maintenance of the 7.6-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 7.6-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 7.6-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
125 mph (200 km/h) winds in any operational position in moderate coastal/industrial
areas. Severe conditions require additional protection.
8. Should it be expected that winds will exceed 125 mph (200 km/h), it is recommended
that Andrew antennas be steered to specific azimuth and elevation orientations to mini-
mize wind forces upon the structure and thereby increase the probability of survival.
Position the antenna to an elevation of zero degrees. The azimuth jackscrew should be
placed in the center of its travel. It is recommended that all cross-axis waveguide and
coaxial cables are secure such that high winds will not cause excessive flexing.
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.
