ISM magnetic antenna
The omnidirectional antenna designed to receive ISM signals operates in the 868 MHz band and is ideal for building IoT networks. ISM antennas are often used in a variety of applications such as wireless sensors, monitoring systems, remote control, wireless devices for industrial process control and automation, and many more. The magnetic base allows easy installation on metal surfaces without the need for additional mounting accessories.
An RG58 cable is routed from the antenna and terminated with an SMA (m) connector.
Connector specifications SMA:
These are high-frequency connectors with screw connection mechanisms. The characteristic impedance of the connector is 50 Ohm and the operating frequency range up to 18 GHz. There are two types of SMA connectors, namely SMA and RP-SMA. Most of the current cellular routers are equipped with SMA connectors for connecting Wi-Fi / 2G / 3G / LTE / GPS antennas terminated by proticates. It is also used as a standard connector in RF measuring technology. They are characterized by high reliability, durability, high mechanical stability and optimal electrical properties.
Cable specifications RG58:
The RG58 coaxial cable is compatible with connectors applicable to a 5 mm cable diameter. It is mainly used for the 0-1 GHz frequency range, it can also be used for higher frequencies, but at the cost of higher attenuation. The characteristic impedance of the cable is 50 Ω. The reduction factor is fixed at 0.66. The most common cables of this type have a temperature range of -20 to 75 ° C. This cable is suitable for external WiFi / GPS / GSM antennas. It is also often used for creating cable adaptors with connectors such as BNC / FAKRA / FME / N / SMA / TNC and others. There are also specially modified types of RG58 cables for outdoor use, which are UV resistant, as well as for use in extreme conditions. There are made of different materials, different qualities.
