6.2 Installation of Antenna Unit
Mounting considerations
Install the antenna unit referring to the antenna installation diagram at the end of this manual.
When selecting a mounting location for the antenna unit, keep in mind the following points:
• Do not shorten the antenna cable (10 m cable fitted to the antenna).
• The length of the whip antenna for the NX-3E should be no longer than 1.2 m and no larger
than 5 mm in diameter to prevent antenna damage. Do not use a 2.5 m whip antenna. Use
spring washer (supplied) for whip antenna.
• Do not install the antenna unit within beamwidth of the radar.
• If the antenna cable is to be passed through a hole which is not large enough to pass the
connector, you may unfasten the connector with a needle nose pliers and 3/8-inch open-end
wrench. Refasten it as shown in Figure 6-2, after running the cable through the hole.
• If you install the antenna unit except the NX-3E and the NX-3H, contact your dealer.
