Omnidirectional internal GSM antenna 

Omnidirectional internal antenna with SMA connector for GSM technologies. The antenna operates in bands 900/1800 MHz. This type of antenna is most often used for connection to terminals, modems or routers that are equipped with an SMA (f) connector.

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. 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.
