n Wiring External Antenna
l Specification for Extension Antenna Cable (Only by order of option)
• Specification: 8D-SFA(PE)
• Outside Diameter: 11.1 mm
• Minimum Bend Radius: 67 mm (when fixing)
167 mm (when wiring)
• Cable End Treatment: N type connector, one end is male and the other is female.
* “When fixing” shows the bending radius for fixing (the state is maintained for a long time).
“When wiring” shows the bending radius while checking the wiring position. This bending
radius is set larger than that for fixing in order to prevent damage to the cable because the
cable is likely to be repeatedly bent when checking the final wiring position.
l Wiring of Extension Antenna Cable
1. Use the provided extension antenna cable to connect the antenna connector with the ex-
ternal antenna. Tighten the connector of the antenna extension cable with a torque of 2 to 3
N∙m. Refer to the specification about the limitation of bend radius when fixing or wiring.
2. When using two extension cables, the provided arrester should be inserted between these
cables.
3. Before the wiring work, confirm the polarities (male/female) of the connectors of antenna,
extension antenna cable, and arrester.
Tighten the connector of the antenna extension cable with a torque of 2 to 3 N∙m.
4. Protect the connectors of antenna, extension antenna cable, and arrester as necessary.
See “A3.2.4 Mounting Antenna and Wiring.”
5. Fix the extension antenna cable to the appropriate structure to protect the cable from the
vibration, wind, and so on.
