Omnidirectional adhesive GSM antenna
Omnidirectional adhesive antenna operates in bands 800/900/1700/1800 MHz. Used in vehicles to connect to cellular modems and routers or signal repeaters. The antenna is supplied with a 3 m long RG174/U cable, which is terminated with an FME(f) connector. Comes with 3M double-sided tape for easy mounting on glass or plastic.
Connector specifications FME: FME coaxial connectors are characterized by high reliability and mechanical stability. The characteristic impedance of the connector is 50 Ohm and the operating frequency ranges up to 2 GHz. Temperature range is -65 °C to +155 °C. Thanks to their compact size and long longevity, the FME connectors are used in the field of mobile communications as well as for GSM antennas. They are suitable for installation in vehicles as well. 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. Technical parameters can be found in the attached datasheet.
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.
