Lynx NGT-9000s
Installation Manual
2.3.2.3 Antenna Cable Assembly
The instructions below provide the information necessary to assemble the contacts required to connect the
coaxial cable to the unit. The other end of the cables typically has TNC Adapters installed that connect to
low loss RF cables. See Figure 2-7.
All models of the Lynx NGT-9000s are required to have GPS and Omnidirectional (UAT) cable
connections (A5 & A4). Models with TAS have three cables connecting to A1, A2, and A4. Models with
Diversity have one cable connecting to A2.
NOTES
1.
The cable attenuation and VSWR ratings must be verified to not
exceed the specified values.
2.
Place 4-6 inches (10.2 to 15.2 cm) of heat shrink tubing over each
antenna connector and cable to add strain relief and alleviate stress
caused by aircraft vibration.
When routing antenna cables, observe the following precautions:
•
All cable routing should be kept as short (do not exceed maximum cable length detailed in the
vendor tables, paragraph 1.6, in the General Information section) and direct as possible.
•
Avoid sharp bends (do not exceed maximum bend radius detailed in the vendor tables in the General
Information section, paragraph 1.6.
•
Avoid routing cable near power sources (e.g., 400 Hz generators, trim motors, etc.) and near power
for fluorescent lighting.
•
Avoid routing cable near ADF antenna cable (allow at least a 12-inch (30.5) separation).
