3.3.4 Location Requirements for GPS Antenna Mounted in the Rural Area

The Horizon 3G-n fiber & Horizon 3G-n mini is usually mounted on a pole when the system is located in a rural area. In this case, the GPS antenna can receive good satellite signals when it is installed on the top of a hill.

However, the GPS antenna must be protected from being struck by lightning. High installation position for the GPS antenna easily leads to damage to the GPS antenna and GPS receiver. When the GPS feeder is routed along the pole, the feeder is conductive to the lightning surge which is released through the pole.

Figure 3-6 shows the installation positions for the GPS antenna mounted on a pole. Positions 1 and 2 are preferred while positions 3 and 4 are prohibited.

Caution:

In Figure 3-6, when the GPS antenna is installed at position 2, space between the GPS antenna and the Horizon 3G-n fiber & Horizon 3G-n mini must be within 2 m in vertical direction.

a) Check if the core wire and the shielding layer of the feeder are short-circuited using a multimeter.

If they are short-circuited, check if the feeder is damaged.

b) Short-circuit the core wire and the shielding layer at one end of the feeder. Then measure the resistance between them.

If the resistance is infinite, it shows that the feeder is broken.

2) After you confirm that the feeder is faulty, replace the faulty feeder with a new one.


3-26

3.6.3 Installation Requirements

Adhere to the following principles when you install the feeders:

z The path for leading the feeder from the installation position to the equipment should be cleared. The feeders should be properly routed and fixed. Reliable waterproof and anti-corrosion measures must be taken.

You can make a waterproof curve by bending the feeder in a natural manner at the point where the feeder enters the equipment room. The bending radius is 20 times longer than the feeder diameter. The vertical distance from the lowest point of the waterproof curve to the entrance must not be less than 200 mm to prevent rain from entering the room.

z Protect both ends of feeder connectors with strong materials such as packing bags for boards to prevent damage to the connectors during feeder distribution.

z When installing the GPS antenna on a roof, fasten the feeder using plastic clips with steel nails along the root of the enclosing wall on the roof. The spacing of plastic clips must be 1 m. The direction of their heads must be interlaced regularly.

z When the feeders are routed along a cabling ladder, fixing clips must be used every 2 m.

z Try to uncoil the feeder and avoid bending it when routing a feeder. If bending is inevitable, make sure that the bending radius is at least 20 times larger than the feeder diameter.

3.6.4 Grounding Requirements

The feeder grounding clips and the feeders are installed at the same time. The following describes how to ground feeders in different installation modes:

Note: All the grounding cables are connected to the nearest grounding bar.

I. Installing the NodeB Outdoors (Excluding Installation on the Rooftop)
