JCG 401 GSM AntennaJCG 401 GSM Antenna is good for all GSM wireless modems or transmitters. It is an external antenna for GSM (Global System for Mobile Communications) devices. It is designed to improve the signal strength and connectivity of GSM devices such as mobile phones, modems, and routers.Product Specifications:Frequency Range（MHz): 824~894 MHz / 1710~1990 MHz, 880~960 MHz / 1710~1990 MHz, 1920~2170MHzBandwidth（MHz): ±5MHzVSWR: (5m) 2.0:1Typical Gain（dBi): 2.0Max Input power:（W）60Input Impedance:（Ω）50Polarization Type: VerticalConnector Type: SMASize: D 10.4 x 55 mmOperating Temperature: -45℃ to 85℃Housing Black A GSM antenna is used to improve the signal strength and connectivity of GSM devices such as mobile phones, modems, and routers. GSM antennas are typically external antennas that are connected to the GSM device via a coaxial cable. They can be mounted on a building or vehicle, or placed on a desk or table. They are used to pick up radio frequency (RF) signals from GSM cell towers and transmit them to the connected device. This allows for better call quality and faster data speeds.There are several different types of GSM antennas, including:Omni-directional antennas: These antennas radiate signals in all directions and are typically used in residential and small office settings.Directional antennas: These antennas focus the signal in a specific direction, which makes them useful in areas with weaker signals or for increasing the range of a signal. They are also known as Yagi antennas.Panel antennas: These antennas are flat and rectangular, and are often mounted on walls or roofs. They are useful in areas with weak signals and have a wide coverage area.Rubber duck antennas: These antennas are small, flexible, and often come with mobile devices such as cell phones. They are less efficient than other types of antennas, but are convenient for portable use.MIMO (Multiple Input, Multiple Output) antennas: These antennas are used in 4G and 5G networks, they have multiple antenna elements and can improve the data rate and reliability of wireless communication.Indoor and outdoor antennas: GSM antennas can be used both indoor and outdoor, depending on the environment and the coverage area needed. Outdoor antennas are more robust and weather-resistant than indoor antennas, but the latter can be hidden more easily. Click Wireless Communication for more products at best price in Bangladesh.
