Cabling and Wiring
All unshielded wire shall be selected in accordance with AC43.13-1B Change 1, Paragraphs 11-76
through 11-78. Wire types should be to MIL-W-22759 as specified in AC43.13-1B Change 1, Paragraphs
11-85, 11-86, and listed in Table 11-11. For shielded wire applications, use Tefzel MIL-C-27500 shielded
wire with solder sleeves (for shield terminations) to make the most compact and easily terminated
interconnect. Follow the wiring diagrams in Section 2.6 as required.
Allow 3 inches from the end of the wire to the shield termination to allow the hood to be easily installed.
Note that the hood is a ‘clamshell’ hood, and is installed after the wiring is complete.
All wiring should be at least 22 AWG, except where otherwise specified. Ensure that all ground
connections are clean and well secured.
2.3.4
Installation of Radio into NTA01-001
Refer to
Mechanical Installation
drawing NTA01\001\952-0.
Remove the cover from the NTA01-001. The necessary cables and screws for connecting and fitting the
radio are inside the unit in anti-static bags.
Attached to the inside of the unit closest to the external connectors is the RF coaxial cable connector, the
power supply connector, and a 15-pin ribbon cable (J102), and at the other end of the unit is a 25-pin
ribbon cable. These should be attached to the appropriate connectors on the radio.
Note
: If an XTL-series radio is to be installed, the 15-pin ribbon cable (J102) is not used, and must be
removed to allow proper installation of the radio.
Inside one of the bags there are four panhead screws that should be used to attach the radio inside the NTA01-
001 through the cover, and also sufficient flathead screws to fasten the cover into place.
Note
: In some cases it may be necessary to use a 90º adaptor for the coaxial cable.
