High Performance 4G Fiberglass Antenna Models

　　Characteristics and model selection of 4g external antenna

　　When choosing a suitable antenna for the equipment, first of all, it is necessary to determine whether to use an internal or external antenna according to the product structure.

　　1. The main characteristics of 4g external antenna

　　High gain, less environmental impact, can be used as a standard product, save development progress and occupy space, and affect the beauty of the product

　　2. Model selection of 4g external antenna

　　It is necessary to determine the signal coverage direction of the equipment. The signal coverage direction is determined by the radiation pattern of the antenna. According to the radiation direction of the antenna, the antenna is divided into omnidirectional antenna and directional antenna.

　　Suction cup antenna: The gain is relatively high, and the biggest feature is that it contains a strong magnetic suction cup. It is very convenient to install and fix, but the suction cup must be adsorbed on the metal surface.

　　In the field of wireless modules, suction cup antennas are often used in conjunction with wireless antenna modules to achieve the purpose of increasing the communication distance of wireless modules, such as wireless smart meter reading, vending machines, express boxes, car radios, etc.

　　Copper rod suction cup antenna: similar to the general whip suction cup antenna, but the advantage over the whip suction cup is that it uses a large-diameter all-copper radiator, which has low loss, high antenna efficiency, and wide bandwidth coverage.

　　Suitable for data transmission stations with relatively high performance requirements, medium-distance map transmission, etc.

　　Rubber stick antenna: the most common external wireless antenna, with moderate gain and relatively low price, commonly used in wireless communication control modules, wireless routers, data transmission stations, etc.

　　You can choose a wireless antenna of appropriate size according to the requirements of the installation space. The selection of antenna size is related to gain. Generally, the longer the length of the same frequency band, the higher the gain.

　　Fiberglass anti-corrosion antenna: Among omnidirectional wireless antennas, fiberglass anti-corrosion antennas have better performance. The core is a full copper vibrator, and a balanced explosion-proof switch is used, which is less affected by the environment;

　　The casing is made of high-quality fiberglass anti-corrosion, has excellent three-proof characteristics, and adapts well to extreme geographical environments. It is especially suitable for ultra-long-distance gateway IP signal coverage, image transmission, etc.

　　External directional antennas are generally used in environments with long communication distances, small signal coverage areas, and high target density. The extreme case is point-to-point long-distance communication.

　　Tablet antenna: high efficiency, small size, easy installation, and can combine gain and radiation source area. It can be used for indoor and tunnel signal coverage, medium-distance signal transmission, image transmission, and signal passing through walls.

　　Yagi antenna: very high gain, slightly larger size, strong specificity, and attention must be paid to the position of the antenna when using it. It can be used for ultra-long-distance signal transmission, image transmission, and direction finding.

　　Multi-period antenna: ultra-wideband antenna, with very wide bandwidth coverage, the bandwidth can reach 10:1, commonly used in signal enlargement, indoor distribution, and elevator signal coverage.
