NOTE: Other accessories have been packed in the packing box.

Install GPS Antenna

Read the following GPS antenna installation requirements before installing it on the base station.

  • No major blocking from buildings in the vicinity. Make sure the space atop is at least 45 degrees unblocked by any buildings.
  • Avoid installing the GPS antenna in the vicinity of any other transmitting and receiving devices, to avoid interference.
  • The GPS antenna should be installed within 45 degrees to the lightning rod.

The GPS antenna system is assembled in manufacturing before packing. The only installation step is to fix the GPS mounting bracket on the base station with the M4*14 screws.

Installation

NOTE : The base station may adopt different models of GPS antenna, so the GPS antenna may not the same as above figure. But the installation steps that fix it on the base station is the same.

Weatherproofing

To protect the connection points from weather and climate, clean each connection point before installing cold shrink tubes, per the following figure.

  1. Insert the cable into the cold shrink tube.
    Weatherproofing

  2. Tighten the connector.
    Weatherproofing

  3. Push the cold shrink tube to the top joint, and pull out the strip.

  4. Ensure the cold shrink tube is tightly fitted with the connection.
    Weatherproofing

Pole Mounting

Check to ensure the diameter of the pole is in the range of 1.6 inches to 2.8 inches (40mm to 70 mm). The position of the g NB on the pole should be at least 47 inches (120 cm) in height.

The brackets have been pre-assembled in manufacturing before packing. It includes two parts, one is pre-assembled on the back of device. The other is for pole mounting or wall mounting, as shown in Figure 2-1.

Pole Mounting Bracket

Installation

Following will introduce how to fix the pre-assembled g NB on a pole.

  1. Put the pole bracket against the pole.
    NOTE the arrow must be upward.

  2. Assemble two omega clamps back and fasten four nuts on the back of the bracket.
    Installation

  3. Hung the g NB (with bracket)on the pole bracket Ensure the hook on the g NB bracket is stuck in the slot.

  4. Fasten the screw on the top of the bracket using a cross screw driver.

After mounting, adjust the g NB to a proper angle by adjusting the adjustable bracket.

Wall Mounting

NOTE : The wall must bear at least 4 times the weight of the g NB.

Take apart assembly bracket first, only remains the wall bracket, as shown in Figure 2-2.

Figure 2-2 Wall Bracket

Wall Mounting

Following steps introduce how to fix the pre-assembled g NB on a wall.

  1. Fit the installation bracket on the wall and mark drilling locations with a marker pen.
    NOTE : the arrow must be upward .
    Installation

  2. Drill two holes at the marked locations and install expansion bolts.
    And then hang the wall bracket on expansion bolts, and fasten with flat washers, spring washers and nuts.
    Installation

  3. From top to bottom, clip the g NB into the hook on the bracket and tighten the pin on the top of the bracket.
    Installation
