Combined LTE/GNSS Mounting Antenna
This combined antenna is designed to receive both LTE and GNSS signals. The LTE part of the antenna serves for connecting to 4G/LTE mobile networks, enabling high-speed data transfer. The GNSS (Global Navigation Satellite System) part of the antenna receives signals from satellite navigation systems such as GPS or GLONASS. This allows for precise determination of the device's position. The antenna operates in frequency bands ranging from GPS/GLONASS: 1575.42/1602 MHz, LTE: 700/800/900/1800/2100/2600 MHz. In connection with the amplifier, it achieves a gain of up to 30 dBi in the GPS band.
The antenna is ideal for use in locations where there is a need to combine accurate positioning with high-speed mobile connectivity. With an IP67 rating, it is suitable for outdoor installation. Two RG174/U cables, each 300 mm long, extend from the antenna and are terminated with SMA(m) connectors.
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.
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.
