4G 2.4G IP67 Wifi SAM Connector Helical Antenna Vertical Polarization

4G 2.4G IP67 Black Rubber Wifi 14 1/4wave Helical Antenna With SAM Connector

Firstly, in the field of communication antenna, antenna is an important part of base station. The connection of the antenna affects the receiving effect of the mobile antenna terminal, and ultimately affects the communication quality of the mobile phone and the transmission speed of the network.

Electrical Characteristics:

Compared with the built-in antenna, the sucker antenna has better standing wave ratio, higher efficiency and no need of customization; Compared with the rubber rod antenna, it has higher gain and longer transmission distance in the same frequency band and structure size. Different installation positions can be selected according to the actual needs. In addition to the above advantages, the sucker antenna also has a wide range of uses, in addition to our daily visible vending machines, express cabinets, car radio, but also suitable for wireless modules and wireless gateways with medium gain requirements.

1. The antenna radiator is made of stainless steel, pure copper, memory alloy and other materials, and its shape is usually whip shaped or rod-shaped. A sucker antenna radiator is actually a monopole (whiplash) antenna, whose arm is perpendicular to an ideal conductor plane (ground). According to the principle of antenna, the resonant frequency of wire antenna is integral multiple of 1 / 2 wavelength. According to the principle of mirror image, the ideal minimum electric size of sucker antenna is 1 / 4 wavelength on the ideal infinite plane. If we want to improve the gain, we can increase the length of antenna radiator (integral multiple of 1 / 4 wavelength) by adding inductance in the middle.

2. The function of high-intensity magnetic sucker is to fix the whole antenna and ensure that the sucker antenna is in conductive contact with the absorbed metal.

3. Feeders generally have RG series (RG58, RG174), 3D wire, etc.

4. The common types of antenna interfaces are: n-head, SMA, BNC, TNC, 1-pex and so on. Among them, the commonly used connectors of sucker antenna are n-head, SMA, BNC, TNC and so on, which are male and female. When choosing the antenna, you must buy the connector matching with the equipment.
