Omnidirectional GSM/UMTS/LTE Antenna
This omnidirectional magnetic antenna is designed for reliable signal reception across GSM, UMTS, and LTE networks. It operates within a wide frequency spectrum ranging from 690 MHz to 2400 MHz. The antenna features a strong magnetic base for easy mounting on metal surfaces. The package includes a 5m RG174/U cable terminated with a standard SMA (m) connector, ensuring a simple connection to modems, routers, or industrial terminals.
SMA Connector specifications:
SMA (SubMiniature version A) connectors are high-frequency interfaces featuring a threaded coupling mechanism. The connector has a characteristic impedance of 50 Ohm and an operating frequency range of up to 18 GHz. There are two main variants: standard SMA and RP-SMA (Reverse Polarity). SMA connectors are the industry standard for most contemporary cellular routers, used to connect external Wi-Fi, 2G, 3G, LTE, and GPS antennas. In addition to telecommunications, they are widely utilized as a standard interface in high-frequency measurement technology.
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.
