1.3 SYSTEM OVERVIEW
The transceiver is constructed in a modular configuration. Common to the configuration
for any frequency band of operation is a base module, which provides the M&C, Power
Supply, and Reference function. A Band-specific BUC module is mounted to the base
module with clip-type fasteners. An internal bias tee provides a 10 MHz reference and
bias voltage for an external LNB.

Chapter 2. Installation
2.1 UNPACKING AND INSPECTION
Inspect shipping container for damage. If shipping containers are damaged, keep them
until contents of shipment have been carefully inspected and checked for normal
operation.
Remove the packing list from the outside of the shipping carton. Open the carton and
remove the contents, checking the contents against the packing list. Verify completeness
of the shipment and that the unit functions correctly. If damage is evident, contact the
carrier and Comtech EF Data immediately and submit a damage report. If the unit needs
to be returned to Comtech EF Data, use the original shipping container.
2.2 INSTALLATION AND OPERATION
The Common Module of the MBT-4000B may be located near or on the antenna. The
band-specific BUC is latched into place on top of the Common Module (M&C, Power
Supply, Reference). Cables to the antenna and IDU complete the installation.
