Pa r t Q ty . Tie-wrap scre w mount 6 T erminal str ip connectors 5 Sensor module to ADCU power wire f errite 1 #4-24 thread-f orming screws 4 Choosing Component Locations The major considerations in locating the T racV ision components are described below .
Choosing the Best Location for the T racVision Antenna There ar e several factors to consider when choosing the location for the T racV ision antenna. • Since the T racV ision antenna requires a clear view of the southern sky to receive satellite signals, the ideal antenna site has an unobstructed view of the horizon/satellite all around.
Radar Concerns The T racV ision antenna must be kept out of line with nearby radars, as their energy levels may overload the antenna’s fr ont- end circuits. In an ideal installation, the antenna is mounted four feet (1.2 m) above and four feet (1.2 m) away from the radar (measured fr om the center of the antenna dome to the center of the radar).
Choosing the Best Location for the GyroT rac Sensor • Ideally , the sensor module should be mounted as low as possible in the center of the vessel – but NOT in the bilge. • The mounting surface should be free of excessive vibration and flexing. • Maintain at least four feet (1.
2.2 Mounting the T racVision Antenna 1. Make sure that you have chosen a suitable mounting location based upon the guidelines in “ Choosing the Best Location for the T racV ision Antenna” on page 12 .
6. Remove and save the three scr ews securing the radome to the baseplate. Carefully lift the radome straight up until clear of the antenna assembly and set it aside in a safe place. If you bring the radome topside, be sure to secur e it with a lanyard so that it does not fall overboard.
10. Position the baseplate assembly in place over the mounting holes and cable access, with the baseplate’s “Forward” arr ow (shown in Figure 2-6) pointing toward the bow . Ensure that all holes line up and that the connectors are center ed over the cable access.
13. Place the antenna baseplate over the holes drilled in the foundation, ensuring the “Forward” label (shown in Figure 2-6) points towar d the bow . 14. At each of the four baseplate mounting holes, place a 1 ⁄ 4 " flat washer on a 1 ⁄ 4 "-20 bolt and insert the bolt into the hole from above, as shown in Figure 2-8.
