QWB490

The QWB490 antenna is a highly efficient vertical polarized omni-directional antenna that has been developed to provide significant wideband gain, good front-to-back ratio and optimized radiation angle. This type of antenna is most often used for Wireless Broadband applications such as 3G, 4G, LTE and Wi-Fi, and in a wide range of Point-to-Point communications systems. The QWB490 antenna also supports Point-to-Multipoint applications, providing a cost-effective solution for both broadband and narrow band communications. This antenna can be deployed in both indoor and outdoor applications, making it an ideal choice for many commercial and industrial applications.

The QWB490 antenna of RF Antennas uses a high quality aluminum sleeve combined with strong shell domes and a ground plane. This construction ensures that the antenna has high electrical performance over a wide range of frequencies. It is also designed to achieve excellent wind loading, as well as excellent temperature stability. The antenna also features a molded base that eliminates the need for a dedicated grounding plane, making installation and maintenance simple and fast.

The antenna\'s working principle is based on the fundamental concept of radiating a radio signal in a specific direction. The base of the antenna contains a series of radiating elements, which, when excited by a signal, cause the antenna to emit an electromagnetic field. The field propagates outward in all directions, and the shape of the field depends on the shape and structure of the antenna. The design of the QWB490 antenna ensures that the field has an optimum radiation angle with a near perfect gain, making it ideal for external applications.

The antenna is also designed to maximize power efficiency, operating at very low power levels and still achieving high output power. The result is a highly efficient antenna with excellent performance characteristics. Its modular construction and easy installation make it suitable for all applications including small to medium wireless networks. This highly durable antenna is also designed to withstand the most extreme conditions, making it a reliable choice for all environments.

The QWB490 antenna of RF Antennas is the perfect solution for applications that require extended coverage and long range communication, such as home and office networks, WISPS (Wireless Internet Service Providers) and other applications. With its high gain, reliability and efficiency, this antenna is an excellent choice for virtually any wireless communication need.
