Omnidirectional GSM antenna Magnetic 50
Omnidirectional antenna for GSM technologies. The antenna operates in bands 900/1800 MHz. It is suited for modems/routers. The magnetic base allows the antenna to be mounted on the car roof or other metal surfaces. The antenna is supplied with a 3 m long RG174 / U cable, which is terminated with connector MCX (m) 90 °.
Connector specifications MCX:
These are coaxial connectors with a latch mechanism. They are compatible with SMB connectors, but are 30% smaller than SMB connectors. The dimensions of the internal contact and the insulator are the same. The impedance of the connector is either 50 Ohm with an operating frequency range up to 6 GHz or 70 Ohm with an operating range up to 3 GHz. They are characterized by high reliability and mechanical stability. They are also used as standard connectors in GPS devices, WLAN networks, fixed and mobile communications.
Cable specifications RG174 / U:
The cable labeled RG174 / U is a much cheaper variant of a coaxial cable that is compatible with connectors applicable to a cable diameter of 2.8 mm. It is mainly used for the frequency range 0 - 1 GHz, it can also be used for higher frequencies, but at the cost of higher attenuation – see the attached attenuation table below. The characteristic impedance of the cable is 50 Ω. The reduction factor is fixed at 0.66. The operating temperature range is -20 to 80 °C.
It is most often used for creating cable adaptors with connectors such as BNC / FAKRA / FME / MCX / MMCX / N / SMA / SMB / SMP / TNC and others. It is ideal for short and bending stressed connections in measuring and telecommunications technology, for GPS / GSM / WLAN antennas, antenna leads etc.
