Feed Installation

The 4.5-Meter Earth Station Antenna requires the installation team to perform the assembly in the sequence presented below. Moreover, this sequence should be reviewed beforehand to ensure a smooth installation. Use the following checklist to veri- fy and/or determine the installation sequence. Throughout the checklist certain part num- bers will be used. Those part numbers describe the antenna currently being installed. The ES45T-R is a receive-only 4.5-Meter Earth Satellite Antenna with a tripod mount. The ES45T-T is a transmit/ receive 4.5-Meter ESA with a tripod mount.

Refer to Foundation Specifications for guidance in preparing the location and the instal- lation of the 4.5-Meter Earth Station Antenna foundation.
