50 millimeters dia.) In the mounting platform. See the outline drawing.
2.Detach the antenna housing cover from the antenna housing by loosening four
fixing blots. The antenna housing cover fitted with the transceiver module can
be stored in a convenient place until the wiring to the antenna unit is done.
3. Place the antenna bousing on the mounting platform and orient it as shown in
Figure 6-6.
4. Insert four M12 60 hex head bolts with the seal washers from inside the ante-
nna housing, to prevent the bolts from contacting the transceiver module. Install the
seal washer with the larger diameter next to the head of the bolt. Coat flat and
spring washers and nuts and then use them to fasten the antenna housing to the
mounting platform. Finally, coat exposed parts of nuts, bolts and flat and spring
washers as shown in Figure 6-7.
