1.2.2 Shelter Requirements
The shelter location depends primarily on the maximum cable run allowed and on the desired location for
the DME antenna. An RF transmission line of 2" foamflex cable (with Type N connectors at each end),
one cable for the monitor antenna made up of 1/4" foamflex (with a Type N connector at one end and a
TNC male connector at the opposite end), and one AC cable for the OB Lite may be supplied with the
DME equipment. These cables are 35 feet long. When the requirements exceed 35 feet, company
engineering personnel can provide the necessary planning to determine the requirements.
The DME ground equipment is designed to operate continuously and unattended, but space must be
allocated for maintenance personnel and their equipment.
1.3 Unpacking and Repacking
The DME electronic subsystem is shipped unassembled. Only general precautions can be given because
the crating and unpacking depends upon destination and what optional equipment is included. Most items
are packed separately in individual containers; these are then grouped for crating. Each crate contains a
packing list which details what equipment is enclosed in the crate. Unpack the equipment and visually
inspect each item for accuracy and damage, but DO NOT REMOVE any ESD protective wrapping.
Report any damage immediately. After inspection, repack each item to prevent damage. During
installation, unpack items as they are needed.
