30 m. • The output from a funnel or exhaust vent decreases aerial performance and hot gases can damage the radiator. The antenna unit must not be installed where the temperature is more than 55° C. • The antenna unit can be installed on the bridge, a common mast, or the radar mast. (c) Radar mast(b) Common mast (a) On bridge Installation procedure Refer to the outline drawing at the back of this manual for the dimensions. Make five holes in the platform. Four holes to fasten the antenna unit and one hole for the signal cable. How to fasten the radiator to the radiator bracket See the packing list at the back of this manual for the installation materials. 1. Remove the radiator cap from the radiator bracket. 2. Apply the silicone sealant to the surface of the antenna radiator and the radiator bracket. See the figure shown below for the location. RADIATOR BRACKET Coat grey area with silicone sealant. Groove Radiator (top view) Coat hatched area with silicone sealant. 10mm ANTENNA RADIATOR (bottom view) (Radiator type: XN-10A) (Radiator type: XN-12A) 3. Apply the silicone sealant to the threads in the four holes on the antenna radiator. 4. Apply the grease to the O-ring and set the O-ring to the radiator bracket. 5. Set the antenna radiator on the radiator bracket. 6. Apply the silicone sealant to the radiator bolts (4 pieces). Fasten the antenna radiator to the radiator bracket with the radiator bolts, flat washers and spring washers. Antenna Flat washer Spring washer Hex head bolt (M8 x 30) Radiator bracket Apply silicone sealant to bolts. radiator O-ring Apply silicone sealant to threaded holes How to fasten the antenna radiator to the radiator bracket How to install the antenna unit You can install the antenna unit by one of the two methods shown below. • Use the outside holes • Use the inside holes How to use outside holes of the antenna housing Use the hex head bolts (supplied) to install the antenna unit as shown in the illustration below. 1. Put the rubber mat (supplied) on the platform. Ground terminal Rubber mat Bow mark Location of rubber mat 2. Put the antenna unit on the rubber mat. Align the position of the antenna unit as shown in the illustratrion below. SternBow Antenna unit CAUTION Do not lift the Antenna unit by the radiator; lift it by the housing. The radiator may be damaged. 3. Set four hex head bolts (M12x60, supplied) and seal washers (supplied) from the top of the antenna housing, as shown below. Hex bolt Seal washer Flat washer Spring washer Nut How to set the antenna unit chassis 4. Set the flat washers (M12, supplied), spring washers (supplied) and nuts (supplied) to the hex head bolts. Tighten by turning the nuts. Do not tighten by turning the hex head bolts, to prevent damage to the seal washers. Antenna unit Mounting platform Silicone sealantFlat washer Rubber mat Seal washer Silicone sealant Spring washer How to fasten the antenna unit to the platform 5. Apply the anticorrosive sealant to the flat washers, spring washers, nuts and visible parts of bolts. 6. Prepare the ground point on the platform. Use an M6x25 bolt, nut and flat washer (supplied). The ground point must be within 300 mm from the ground terminal on the antenna unit. 7. Run the ground wire (RW-4747, 340 mm, supplied) between the ground terminal and the ground point. 8. Apply the silicone sealant to the ground terminal and ground point as shown below. Hex bolt Flat washer Ground wire Spring washer Flat washer Hex nut Silicone sealant OR GROUND POINT Ground Hex nut Spring washer wire Flat washerHex nut Weld here. GROUND TERMINAL Silicone sealant Ground wire antenna unit How to apply the silicone sealant to the ground point and ground terminal How to use the inside holes of the antenna housing This method requires removal of the RF unit from the antenna unit to access the inside fixing holes. Use four hex head bolts, flat washers, spring washers and nuts (local supply) to install the antenna unit. Check the length of bolts before you install. 1. Loosen four bolts on the cover to open the antenna unit. 2. Disconnect the connector connected between the upper chassis and the lower chassis. 3. Remove two hex head bolts (M8x25) to separate the upper chassis from the lower chassis. 4. Loosen four pan head screws to remove the cover from the pc board. 5. Remove the connector from the RF unit. 6. Loosen four hex head bolts to remove the RF unit. 1-14 Antenna unit chassis, upper chassis separated 7. Set the corrosion-proof rubber mat (supplied) to the support platform. 8. Cut the rubber bushings in the fixing holes and put four bolts from the inside of the lower chassis. Fasten the lower chassis to the support platform with the spring washers, flat washers and nuts (local supply). Apply the silicone sealant to the flat washers, nuts and visible parts of bolts. 9. Assemble the RF unit, cover and chassis. 10.Set four caps (supplied) into the outside fixing holes. 11.Prepare the ground point on the platform. Use an M6x25 bolt, n...
