2.5.3 Antenna Cable
Use a high quality 50 ohm coaxial cable, such as RG400 or RG142B. When routing the cable, ensure that
you:
 Route the cable away from sources of heat.
 Route the cable away from potential interference sources such as ignition wiring, 400Hz genera-
tors, fluorescent lighting and electric motors.
 Allow a minimum separation of 300mm (12 inches) from an ADF antenna cable.
 Keep the cable run as short as possible.
 Avoid routing the cable round tight bends.
 Avoid kinking the cable even temporarily during installation.
 Secure the cable so that it cannot interfere with other systems.
2.5.4 TY91 TNC Antenna connection
The VHF Com radio uses a solder/crimp TNC connector, Amphenol 31-2.
This section describes the technique for attaching the antenna cable to the supplied TNC connector.
The supplied connector can be completed using a wide range of commercial crimp tools (for example the
Tyco 5-1814800-3). The die apertures for the inner pin and the outer shield should be approximately 1.72
mm and 5.41 mm respectively.
1. Strip back the coax cable to the dimensions in the table, as shown in the diagram below. Slide 25
mm (1 inch) of heat shrink tubing over the cable.
2. Slide the outer crimp sleeve over the cable – it must go on before securing the center contact.
3. Crimp the center contact to the cable.
