2.Detach the antenna housing cover from the antenna housing by loosening four fixing bolts. The antenna housing cover fitted with the transceiver module can be stored in a convenient place until the wiring to the an- tenna unit is done.

3.Place the antenna housing on the mount- ing platform and orient it as shown in Fig- ure 6-11.

4.Insert four M12 x 60 hex head bolts with the seal washers from inside the antenna housing, to prevent the bolts from contact- ing the transceiver module. Install the seal washer with the larger diameter next to the head of the bolt. Coat flat and spring wash- ers and nuts and then use them to fasten the antenna housing to the mounting plat- form. Finally, coat exposed parts of nuts, bolts and flat and spring washers as shown in Figure 6-12.

Note: Tighten the bolts by their nuts to pre- vent damage to the seal washer. Do not turn the bolts to secure the antenna housing.

Connections

Only the signal cable runs from the display unit to the antenna unit. Make the hole for passing the cable through the bulkhead or deck at least 20 millimeters diameter. In order to minimize the chance of picking up electrical interference, avoid where possible routing the signal cable near other onboard electrical equipment. Also, avoid running the cable in parallel with power cables. Pass the cable through the hole and apply sealing compound around the hole for waterproofing.

The procedure for connecting the signal cable to the antenna unit is as following.

1.Through a pipe or waterproof cable grand fitted on the wheelhouse top or bulkhead.

2.Unfasten four screws at bottom of the scan- ner base to remove the cable gland assem- bly.

3.Pass the signal cable through the antenna base and the cable gland assembly (re- moved in step 2.)
