Omnidirectional GPS and GLONASS antenna
Omnidirectional internal GPS and GLONASS antenna. The antenna operates in two bands, 1545.72 and 1602 MHz. The GLONASS antenna reaches up to 30 dBi gain when combined with an amplifier. It is used, for example, in cars for connection to modems, routers, navigation and tracking systems. Easy installation is ensured by 3M tape, which is part of the antenna. A cable with a length of 5 m is attached to the antenna, which is terminated with SMA (m) connector.
It is not advisable to place the antenna on a metallic substrate. Location on the metal cause change of radiation pattern and also basic parameters of the antenna.
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.
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.
