Antenna internal GSM/UMTS
Omnidirectional internal antenna is suitable for usage with GSM/UMTS/LTE technologies and operates on 850/900/1700/1800/1900/2100 MHz frequency. It is suited for modems/routers. The antenna is supplied with a 100 mm RF 1.37 cable terminated with and SMA(m) connector. Easy installation is ensured by 3M tape, which is part of the antenna.
Connector specifications SMA:
These are high-frequency connectors with screw connection mechanism. 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. The connection and disconnection of the connectors is guaranteed for up to 500 cycles. Temperature range is -65 °C to +165 °C. 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 RF 1.37:
The RF 1.37 coaxial cable is compatible with connectors that are applicable to a 1.37 mm cable diameter. Due to its features and size, it is widely used in applications that require high-frequency transmission using miniature coaxial connections. It is suitable for applications involving RF communication equipment, as well as electronic measuring instruments. It is most often used for creating cable adaptors with connectors such as U.FL / SMA / FME / MCX / TNC and others. The resulting cable adaptors are most often used to connect external antennas to eg cellular modules or IoT / NB-IoT / WiFi / GNSS and other RF devices. There are also specially modified types of RF 1.37 cables for outdoor use, which are UV resistant, as well as for use in extreme conditions. There are made of different materials, different qualities.
