Directional active GPS antenna

The directional antenna with a built-in magnet is designed to receive a signal in GPS technology. It operates in the 1575.42 MHz band. In combination with an amplifier, this active antenna achieves a total gain in the GPS band of 30 dB. Thanks to the degree of protection IP67, the antenna is also suitable for outdoor use, it can be mounted on the roof of the car. It is used for navigation and tracking systems, electronic books and other devices. The antenna includes a 5 m long RG174 / U cable, which is terminated with an MMCX90 ° (m) connector.

Connector specifications MMCX: 

These are coaxial connectors with a latch mechanism, which are compatible with MCX connectors but have a smaller size. The characteristic impedance of the connector is 50 Ohm and the working frequency range up to 6 GHz. Operating temperature range -65 °C to + 165 °C. They are characterized by high reliability and mechanical stability. They are also used as standard connectors in GPS devices, WLAN networks, fixed and mobile communications.

Connector 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.
