Use fixed brackets for fixed installation of outdoor directional antennas or outdoor omnidirectional antennas and outdoor cabinets.
The antenna installation must be about 1m away from the bracket and ensure that it will not be blocked by the bracket in its communication direction; in some cases, a lightning rod must be welded at the top of the bracket, and the height of the antenna should be about 0.5m above the top of the omnidirectional antenna. The site where the spread spectrum communication equipment is installed should have a perfect lightning protection grounding system, and the grounding resistance should be ≤ 5Ω. All antenna positions should be within the protection angle of the lightning rod; also in the power supply equipment to do a good job of power supply lightning protection measures to protect the equipment; in the event of a lightning failure, can timely cut off the power, does not affect the normal power supply of wireless devices, This guarantees that the device will not be damaged.
2. In some cases, a larger diameter grid parabolic antenna needs to be installed, and the specific requirements for the mounting bracket are determined according to the site conditions.
Preparation of wireless device power supply conditions 1. In the equipment room where the wireless monitoring device is installed, there should be a stable power supply for the device.
2. AC 220V power supply system, whose supply voltage fluctuates within +5% to -10% range, frequency is within 47Hz to 63Hz.
3. There should be a three-core AC power socket with a grounding wire in the equipment room for auxiliary equipment such as test instruments.
