Description

A directional Yagi antenna with 18 dBi gain is a high-performance antenna designed to focus radio signals in a specific direction, significantly enhancing signal strength and range. It operates across a wide frequency range—typically 698–960 MHz and 1710–2700 MHz—making it ideal for 2G, 3G, 4G, LTE, and other wireless communication systems. This antenna consists of multiple elements: a driven element, reflector, and several directors, all mounted on a boom. This configuration creates a narrow beamwidth, allowing it to transmit and receive signals over long distances while minimizing interference from other directions. The 18 dBi gain means it can significantly amplify weak signals, making it perfect for rural or low-signal areas. Typically constructed from aluminum, it's lightweight, weather-resistant, and easy to mount on poles or rooftops. Most models come with an N-type female connector and support vertical or horizontal polarization, depending on installation needs. This type of antenna is commonly used for: - Extending cellular coverage in remote areas - Boosting signal for LTE routers and repeaters - Point-to-point wireless links
