BB-LTE046LMS

Revised English Description

The combined screw-mount MIMO antenna is designed for reliable GSM/UMTS/LTE signal reception. MIMO technology increases the capacity and stability of a radio link by using multiple transmit and receive antennas. By leveraging multipath propagation, it delivers higher throughput and a lower error rate. The antenna operates in the 698–960 MHz and 1710–2690 MHz bands, making it suitable for cellular routers, terminals and various RF devices. With an IP67 ingress protection rating, it is fully prepared for outdoor installations. A threaded mounting nut ensures secure, permanent installation - ideal, for example, on the roof of a vehicle. The antenna comes with four 3-meter RG174/U cables terminated with SMA (male) connectors.

RG174/U Cable Specifications

RG174/U is a common type of coaxial cable compatible with connectors designed for a cable diameter of 2.8 mm. It features a characteristic impedance of 50 Ω and a velocity factor of 0.66. The operating temperature range is −20 to +80 °C. This cable type is frequently used to assemble adaptors with connectors such as BNC, FAKRA, FME, MCX, MMCX, N, SMA, SMB, SMP, TNC and others. It is suitable for short runs and installations requiring high flexibility, including measurement and telecommunications equipment, GPS/GSM/WLAN antennas and general antenna feeders.

SMA Connector Specifications

SMA connectors are high-frequency, threaded RF connectors with a characteristic impedance of 50 Ω and an operating frequency range of up to 18 GHz. Two variants exist: standard SMA and RP-SMA. Most modern cellular routers use SMA connectors for attaching Wi-Fi, 2G/3G/LTE and GPS antennas. SMA connectors are also widely used in RF measurement instrumentation.
