4G 5dBi Rubber Duck Antenna With SMA Male Movable Connector

a 4G antenna with a 5dBi gain, designed for use with devices that have an SMA male connector. Here’s a bit more about what this setup entails:

1. 4G Compatibility: This antenna is designed to improve the reception and transmission of 4G signals. It’s especially useful if you're experiencing weak signal strength or looking to enhance the performance of your 4G-enabled device.

2. 5dBi Gain: The 5dBi (decibels over isotropic) gain indicates how well the antenna can focus its signal in a particular direction compared to an isotropic radiator. A 5dBi gain antenna is a good balance between range and directivity, providing a decent boost to signal strength while still covering a relatively broad area.

3. Rubber Duck Design: The term "rubber duck" typically refers to the antenna's shape and construction, which is generally compact and flexible. This design is convenient for portability and can be moved or adjusted easily.

4. SMA Male Movable Connector: The SMA (SubMiniature version A) connector is a common type of RF (radio frequency) connector. The "male" designation refers to the connector type that has a protruding pin. A movable connector allows for some flexibility in positioning, which can be useful for optimizing signal reception.

This kind of antenna is commonly used with devices like routers, modems, and other equipment that benefits from enhanced signal reception. If you're installing it, make sure to position the antenna where it can receive the best signal, and adjust its angle for optimal performance.
