Combined screw mount MIMO antenna

Combined screw mount MIMO antenna designed for GSM/UMTS/LTE signal reception.
MIMO technology is a method of increasing the capacity of a radio link by using multiple transmitting and receiving antennas, which mainly use multipath propagation, thus achieving higher throughput and lower transmission error rate.

The antenna operates in the bands 698-960/1710-2690 MHz. It is suited for cellular routers, terminals and RF devices. The IP67 degree of protection makes it suitable for outdoor use. The antenna has a threaded nut for fixed mounting. As an example, it is ideal for placing on the roof of a vehicle. The antenna is supplied with four 3 m RG174/U cables with SMA (m) connectors.

Cable specifications RG174/U:

The cable labeled RG174 / U is a basic variant of a coaxial cable that is compatible with connectors applicable to a cable diameter of 2.8 mm. 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.

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.
