4.6 Installation procedure
4.6.1 Installing the Transceiver Unit
When mounting the unit, position the transceiver unit as shown, so that a notched part
of the transceiver base is directed towards the aft. This arrangement simplifies cable
fitting and servicing. Also take note of the precautions detailed in paragraph 4.4.1
when you attempt to install the antenna unit.
(1) Drill four fixing holes of 14 mm (12 mm for Radome) diameter on the fitting
surface of a radar platform, as shown in Figure 4.1.
(2) Fit the transceiver unit on the position and fix it using the 12 mm (10 mm for
Radome) stainless bolts prepared as installation materials.
