1. Lifting antenna mast (tower) requirements
(1) Class B vehicles adopt the mode of single pole and double net, and should be equipped with a lifting hydraulic mast (tower). When not working, the whole antenna mast (Tower) it should be fully enclosed in the car body; When working, there is a height of 15 meters;
(2) antenna mast (tower) requires lifting balance without impact. After the antenna mast (tower) rises, it should be able to lock to keep balance and ensure normal operation all the time. After locking, it should have the ability to resist 8-level wind without using ground cable.
(3) the antenna mast can bear an effective vertical load of not less than 300kg.
(4) the main part of the mast is made of high quality, high strength and special aluminum alloy. The surface is treated with anti-corrosion and waterproof of special materials, and the corrosion failure period of the main body is more than ten years in harsh environment such as salt spray, the antenna mast (tower) should also have good waterproof performance and maintenance-free capability.
(5) the antenna mast (tower) should have lightning protection system, have good lightning protection ability, eliminate the threat of thunderstorm to equipment and people, lightning protection system should be able to follow the antenna mast (Tower) automatic lifting.
(6) flickering warning lights shall be set on the top of antenna mast (tower).
(7)GPS antenna should be firmly and reliably installed on the top of the vehicle.
(8) the mast lifting time must reach the specified height within 8 minutes.

2. Installation Requirements of antenna
(1) mobile communication antenna: Class B vehicles are equipped with broadband antenna. Base station antenna bracket should be set to support antenna installation of 3 sectors. It is required that the antenna bracket should be able to control the horizontal orientation and pitch through remote control and wire control. The adjustment range is required: the horizontal angle is not less than ± 60 degrees, and the pitch angle is ± 15 degrees.
The antenna installation parts shall be able to be disassembled and assembled for many times, and the bracket shall meet the antenna installation requirements provided by the buyer. Installation requirements are firm and reliable.
(2) microwave antenna: The microwave antenna bracket should be set, and the antenna bracket should be able to control the horizontal orientation and pitching through remote control and wire control. The adjustment range requires: the horizontal angle should not be less than ± 180 °, pitch angle should be -90 ° ~ +45 °.
(3)GPS: it can be installed firmly and reliably on the top of the vehicle.
(4) antenna mounting parts shall meet the requirements of multiple disassembly and assembly. Installation requirements are firm and reliable.
(5) microwave antenna and mobile communication antenna should be adjustable independently.
(6) the antenna feeder adjustment system should have one-button automatic reset function. Before the lifting tower drops, the tower-loaded equipment can be automatically reset to the initial position, antenna mast (Tower) temporary feeder reinforcement facilities should be set up

3. Feeder System Installation Requirements
(1) for convenience of operation, the electric follow-up wire disc is adopted. The feeder is made into a line row, and multiple feeders are rolled together on the cable tray next to the lifting rod. The winding speed of the cable tray and the moving speed of the lifting rod must be completely synchronized.
(2) the cable tray is sprayed with plastic on the welded surface of the steel pipe with locking device.
(3) lightning protection system should be set on the top of antenna mast (tower), and the lightning protection system should be able to automatically rise and fall with antenna mast (tower).
★Antenna feeder system adopts broadband antenna (2 antenna ports, the frequency band supports 800M-2600M, similar to full-band GSM & DCS & FAD multi-system dual-channel antenna), it is an emergency communication mobile base station composed of fully automatic vehicle-mounted electric mast and 4G/5G multiple RRU antennas.
★The antenna part requires 900M, 1800M and TD-LTE signal to be connected to the rear tower, and the combiner adopts broadband four-in-one combiner, including at least GSM frequency band (885-954MHz), DCS band (1710-1825MHz) and TD-LTE F/A/D band (1880-2600M).
