Omnidirectional antenna for GSM/UMTS/LTE technologies
Omnidirectional antenna for GSM/UMTS/LTE technologies. The antenna operates in bands 700/800/900/1700/1800/2100/2500/2600/2700 MHz. It is suited for cellular routers, terminals and RF devices. The antenna is supplied with two 3 m cables with 2x SMA(m) connectors.
MIMO technology is a method of increasing the capacity of a radio link by using multiple transmitting and receiving antennas, which mainly use multipath propagation, thus achieving higher throughput and lower transmission error rate.
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.
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.
