Section II. INSTALLATION PROCEDURES
2-9 SPECIAL TOOLS AND EQUIPMENT REQUIRED FOR FIELD
INSTALLATION.
No special tools or equipment are needed for installation and initial setup of the BDR.
2-10 INSTALLATION SEQUENCE
(See FO-1.) Perform the following procedure to install the BDR. Cables required for installation are listed in Table 2-2.
FO-1 illustrates the required cable connections.
2-10.1 Antenna/Mast Installation
(Refer to Figure 2-2.) Install the antenna mast and selected antenna as follows:
Ensure proper use of safety tools (work gloves and hard hat) during assembly and disassembly
of antenna and mast.
NOTE
The BDR assembly is shipped from the factory configured for 30-88 MHz operation, with the
appropriate receiver-transmitters and diplexer. If using a different configuration, substitute the
appropriate antenna, receiver-transmitters, and diplexer. Refer to Chapter 6 for antenna and
diplexer removal and replacement. Refer to TO 31R2-2PRC139-1 for changing receiver-
transmitter configuration.
NOTE
The assembled antenna base section/antenna adapter will fit in the mast transit bag (3) so that step
a may be carried out prior to field deployment, if required. When erecting the antennas in high
winds, ensure that a minimum of three personnel are used.
a. Bolt the antenna base section (1, Figure 2-2) to the antenna adapter (2) and connect the antenna ground
strap to its terminal.
b. Select an unobstructed site. Under windy conditions mast raising is made easier if the mast is laid out
on the ground with the base of the mast pointed into wind.
