Antenna TETRA/GPS
Omnidirectional antenna is suitable as receiver of signal in TETRA/GPS. The antenna operates in bands 1575.42/410 MHz. In combination with integrated amplifier, this active antenna achieves a gain of up to 30 dBi in GPS band. It is suitable for use in cars and other vehicles. Two RG174 / U cables with a length of 5 m are attached to the antenna, which are terminated with two SMA (m) connectors.
Cable specifications RG174 / U:
The cable labeled RG174 / U is a basic variant of a coaxial cable that is compatible with connectors applicable to a cable diameter of 2.8 mm. The characteristic impedance of the cable is 50 Ω. The reduction factor is fixed at 0.66. The most common cables of this type have a temperature range of -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. There are also specially modified types of RG174/U cables for outdoor use, which are UV resistant, as well as for use in extreme conditions. There are made of different materials, different qualities.
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. The connection and disconnection of the connectors is guaranteed for up to 500 cycles. Temperature range is -65 °C to +165 °C. 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.
