1. Requirements for elevating electric telescoping antenna mast (tower)
(1) The B-type vehicle adopts the single-pole double-net method, and should be equipped with a lifting hydraulic mast (tower). When not in operation, the entire antenna mast (tower) should be completely retracted into the vehicle compartment; during operation, there are 15 lift height in meters;
(2) The electric telescoping antenna mast (tower) requires lifting balance without impact. After the antenna mast (tower) is raised, it should be able to be locked to maintain the balance, and it should be able to work normally all the time. After locking, it should have the ability to resist the wind of grade 8 without using the ground cable.
(3) The electric telescoping antenna mast can withstand an effective vertical load of not less than 300kg.
(4) The main part of the mast is all made of high-quality, high-strength, special aluminum alloy, and the surface is treated with anti-corrosion and waterproofing of special materials. In harsh environments such as salt spray, the corrosion failure period of the main body is more than ten years, and the antenna mast (tower) should also be used. It has good waterproof performance and maintenance-free ability.
(5) There should be a lightning protection system on the mobile antenna mast (tower), with good lightning protection capability, to eliminate the threat of thunderstorms to equipment and people, and the lightning protection system should be able to automatically lift with the antenna mast (tower).
(6) A flashing warning light should be set on the top of the mobile antenna mast (tower).
(7) The GPS antenna should be firmly and reliably installed on the top of the vehicle.
(8) The mast lift time is required to reach the specified height within 8 minutes.
2. Antenna installation requirements
(1) Mobile communication antenna: Class B vehicles are equipped with broadband antennas. The base station antenna bracket should be set up to support antenna installation of 3 sectors. It is required that the antenna bracket should be able to electrically adjust the horizontal azimuth 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 mounting parts should be able to be disassembled and assembled many times, and the brackets should meet the antenna installation requirements provided by the buyer. The installation requires firm and reliable.
(2) Microwave antenna: a microwave antenna bracket should be installed. The antenna bracket should be able to electrically adjust the horizontal azimuth and pitch through remote control and wire control. The adjustment range is required: the horizontal angle should not be less than ±180°, and the pitch angle should be -90°~+ 45°.
(3) GPS: It can be installed firmly and reliably on the top of the vehicle.
(4) The antenna mounting parts should meet the requirements of multiple disassembly and assembly. The installation requires firm and reliable.
(5) The microwave antenna and the mobile communication antenna should be independently adjustable.
(6) The antenna feeder adjustment system should have a one-key automatic reset function. Before the lifting tower is lowered, the tower-mounted equipment can be automatically reset to the initial position. The antenna tower mast (tower) should be provided with temporary reinforcement facilities for feeders.
3 Feeder system installation requirements
(1) For the convenience of operation, the method of electric follow-up wire reel is adopted. The feeder is made into a wire row, and multiple feeders are wound together on the cable reel next to the lifting rod. The winding speed of the cable reel and the movement speed of the lifting rod must be completely synchronized.
(2) The cable reel frame is sprayed with plastic on the welded surface of the steel pipe, with a locking device.
(3) A lightning protection system should be installed on the top of the antenna mast (tower), and the lightning protection system should be able to automatically rise and fall with the antenna mast (tower).
Electric telescoping antenna mast, mobile antenna mast for sale, antenna tower mast wholesale is provided with a chassis at the bottom end of the antenna mast, which is characterized in that: the antenna vibrator includes more than three vibrator arms, three or more. The upper vibrator arm evenly surrounds the antenna mast and is vertically aligned. Connected to the top of the antenna mast, more than three vibrator arms are supported by the umbrella-shaped frame.
