1.10 EQUIPMENT REQUIRED NOT SUPPLIED
Use Table 1-10 to identify equipment required for installation, calibration, and testing. Refer to Appendix C
for equipment compatible with the Lynx NGT-9000.
NOTE
Equivalent tools, equipment, and hardware may be used.
Table 1-10: Equipment List
ITEM DESCRIPTION
Cables and Wiring: The installer supplies all system wires and cables.
Mating Connector (P1)
• Wires are #22 or #24 AWG as noted on interconnect wiring diagram in
section 2. Use M22759 or equivalent wire and use M27500 or equivalent
for twisted shielded wire for installation.
Antenna Cables
• L-Band and GPS Antenna
Require M17/128-RG400 or equivalent coaxial cable. For the L-Band
antenna the attenuation must not exceed 1.5 dB per cable (including the
connectors). For the GPS antenna, the attenuation should not exceed 10
dB per cable (including the connectors).
NOTE
RG type coaxial cable insertion loss can vary significantly between
manufacturers. Refer to the cable manufacturer's specification sheet for
actual attenuation (insertion loss) for the cable being used.
• Directional Antenna (Required only for models with TAS or TCAS)
The Directional Antenna (NY156 or NY164) requires three cable
assemblies; sum (Sigma Port), bit probe (Probe Port) and difference (Delta
Port). Cable attenuation for the sum and difference ports must not exceed
1.5 db. Table 1-19 identifies U. S. vendors who sell approved cables by the
foot. Table 1-20 provides a cable to connector cross-reference.
M17/128-RG-400 or equivalent may be used for the bit probe cable.
Attenuation for the bit probe cable must not exceed 6 dB.
Note – Antenna NY156 must be used with TCAS. The NY164 cannot be
used with the TCAS.
Circuit Breaker: Installer is responsible for determining appropriate circuit breakers needed to
protect aircraft wiring. Manufacturer recommends the following:
• 2.0 Amp “pull style” circuit breaker for the unit with 28Vdc input
• 3.0 Amp “pull style” circuit breaker for the unit with 14Vdc input
Consumables: Antenna Sealant
• For pressurized aircraft, use a sealant that meets the requirements of SAE
AMS-S-8802 such as Flamemaster® CS3204 class B. For non-pressurized
aircraft, use a non-corrosive sealant that meets the physical requirements
of MIL-A-46146 such as General Electric RTV162.
Surface Preparation
• Alodine® No. 1001 required for installation of the antenna.
Tie Wraps or Lacing Cord
• Commercially available
