The IA-W3 professional indoor omnidirectional roof antenna is a commercial-grade, low-profile signal distribution element engineered to provide uniform, 360-degree wireless coverage within modern interior environments. Utilizing a specialized dome architectural framework often referred to as a “lapa type” layout, this high-integrity antenna is designed for flush ceiling installation to blend seamlessly into corporate offices, commercial centers, and industrial facilities. It functions as an essential, high-performance network node for cellular repeaters, distributed antenna systems (DAS), and wireless telecommunication infrastructures across European distribution networks.
The ultra-wideband electrical engineering of the IA-W3 offers universal compatibility across all major network operators and multi-protocol infrastructures, operating efficiently through a broad 800 MHz to 2,500 MHz frequency range. This expansive bandwidth delivers native support for CDMA, iDEN, GSM, DCS, PCS, UMTS, and 2.4GHz Wi-Fi applications. As clearly illustrated in the product presentation within the file image_df5b02.png, the antenna features an integrated low-loss pigtail cable feedline passing through a threaded central mounting stem, complete with a tightening nut for structural ceiling stability. The internal radiation matrix is vertically polarized, maintaining a strict VSWR of 2.0:1 or less across the spectrum. It delivers a calibrated 2dBi gain metric from 800 to 960 MHz and scales up to a 3dBi gain from 1,700 to 2,500 MHz. While configured for a standard 50 Ω nominal impedance, it can adapt to 75 Ω distribution systems using a specialized N-F RF adapter, ensuring immediate system alignment and fleet deployment readiness.
