The Diamond X200 is a commercial-grade, heavy-duty dual-band base station antenna engineered to optimize vertical omnidirectional radio frequency (RF) propagation and deliver long-range signal stability. Manufactured in Japan using a premium, heavy-duty white fiberglass radome outer shell, this high-gain vertical antenna handles massive electrical loads up to 200 Watts without structural or electrical degradation. It stands as an essential operational asset for centralized dispatch centers, emergency service base stations, marine port command centers, and specialized B2B telecommunication infrastructure distribution channels.
Built to withstand severe environmental exposure and high-wind stresses up to 50 meters per second, the advanced antenna infrastructure utilizes a multi-element stacked phasing layout inside its weatherproof sleeve. The technical configuration operates on a 2 x 5/8-wave profile on the VHF band (delivering an impressive 6.0 dB gain) and a high-efficiency stacked 4 x 5/8-wave matrix on the UHF band (providing an extended 8.0 dB gain) to optimize low-angle radiation patterns. The base assembly terminates in a precision-machined heavy-duty M-J (M-Female / SO-239) connector port and includes industrial-grade mast brackets designed to clamp securely onto mounting poles with diameters ranging from 30 mm to 62 mm.
