August 5, 2011 (Shanghai) – RFS, a global leader in wireless and broadcast communications infrastructure, has introduced a groundbreaking three-band crossover LTE800 polarized base station antenna. This innovative solution combines structural and performance advancements to meet the evolving needs of modern wireless networks. The antenna features a 2.6-meter-long, semi-cylindrical radome that reduces wind load by at least 50% compared to conventional designs. Its internal structure includes 29 vibrators, each paired with a phase shifter, ensuring precise control of the radiation pattern within a tilt range of 2 to 12 degrees. This design guarantees optimal directional symmetry and excellent electrical performance.
The new three-band antenna operates across a wide frequency range, from 790MHz to 2170MHz, making it ideal for LTE800, CDMA850, GSM900, UMTS900, DCS1800, PCS1900, and UMTS2100 applications worldwide. It allows operators to support multiple wireless technologies without increasing the load on existing towers, offering a cost-effective and space-efficient solution. The low wind load also enhances tower stability, especially in harsh weather conditions.
Designed for urban environments where space is limited and interference is a challenge, this antenna delivers superior gain, a low VSWR, and enhanced upper sidelobe suppression. Its variable electric downtilt improves inter-cell interference management, helping operators optimize network performance. “Our goal was to create a compact, high-performance three-band antenna that supports multiple technologies while reducing the weight on the tower,†said Mr. Teppo Lukkarila, Manager of Antenna Products at RFS. “Wind tunnel tests confirmed a wind load of just 590 Newtons, over 50% lower than our main competitor’s product. This design not only meets the demands of dense sites but also ensures reliability and precision.â€
This antenna marks a significant step in RFS’s 4G technology development. The company plans to launch more multi-band antennas in 2011, including dual- and quad-band options, to support various LTE frequency bands globally. Industry experts have praised the antenna for its unique balance of low wind load and high performance. Two of the world’s top ten mobile operators have already certified the product, with more certifications expected soon.
The antenna’s six-port configuration follows industry-standard spacing, simplifying installation and maintenance. RFS continues to lead in wireless infrastructure, providing comprehensive solutions for cable, antenna, and RF conditioning systems. With ISO 9001 and 14001 certification, the company ensures quality, innovation, and customer satisfaction worldwide. From broadcast transmission to microwave communications, RFS remains a trusted partner for operators and system integrators around the globe.
