Omnidirectional combined GSM/WiFi antenna
Omnidirectional combined antenna for GSM and WiFi technologies. The antenna operates in frequency bands 900/1800/2100/2400 MHz. The antenna is suited for cellular modems/routers. The antenna is supplied with cables: 3m of RG174 which is terminated with an SMA (m) connector, and 3m of RG316 with an SMA (m) connector.
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.
Cable specifications RG316 / U:
RG316 coaxial low-loss high-frequency cable that is compatible with connectors applicable to a cable with the outer diameter of 2.49 mm. The frequency range is 0 - 3 GHz. The RG316 cable is often used in radio frequency and telecommunication applications, for the transmission of high frequency signals, and also in wireless devices. It is suitable for applications that require good performance and stability in high temperature environments. The operating temperature of this cable is -55 to + 200 ° C. The shortening factor is set to 0.7.
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. They are characterized by high reliability, durability, high mechanical stability and optimal electrical properties
