Omnidirectional GSM/GPS antenna
Omnidirectional combined antenna for technologies GSM/GPS. The antenna operates in bands 800/900/1575.42/1800/1900 MHz, reaches up to 27 dBi gain when combined with an amplifier in bands GPS and is supplied with two 5m cables with SMA-RP(f pin) and SMB(f) connectors. It is suitable for use in cars and other means of transport. Here it is used for navigation and tracking systems, electronic books and other devices.
Connector specifications SMA-RP:
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.
Connector specifications SMB:
SMB coaxial connectors are characterized by high reliability and mechanical stability. Snap-on mechanism provides fast and reliable connection. The characteristic impedance of the connector is 50 Ohm and the working frequency ranges up to 4 GHz. They are used, for example, to connect wireless WLAN devices, test devices and GSM / GPS / Wi-Fi antennas.
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.
