2.1 INSTALLING THE DISTRIBUTION LINE AMPLIFIER EQUIPMENT
This chapter provides information to install the Distribution Line Amplifier (DLA) and to prepare
the equipment for use.
2.1.1 Unpacking and Inspection
Unpacking the Distribution Line Amplifier does not require special procedures. Use normal
shop procedures to unpack the equipment.
Carefully inspect the shipping containers and equipment. If the containers show damage,
inspect the equipment in those containers with extra care. Do not open containers with
extreme damage.
Check equipment for bent frames, protrusions, and dents. Pay close attention to external
brackets, controls and connectors, because they are especially susceptible to damage during
shipment.
If you find damage to the equipment, notify Andrew Corporation's Customer Service Center at:
• 1-800-255-1479 (Inside the USA)
• 708-873-2307 (Outside the USA)
2.1.2 Proper Installation of Units
The amplifier has a weatherproof NEMA4X enclosure. The layout is optimized for vertical
mounting of the amplifier with the cables connected at the bottom of the amplifier. The
enclosure is accompanied with hanger brackets that are used to mount the amplifier. The
type of fasteners will depend on the construction of the mounting surface.
construction in a concrete tunnel would be to use concrete anchors embedded in concrete.
Once DLA is mounted, the power connections and RF connections can be made next.
