The Diamond X50N is a premium, commercial-grade dual-band base station antenna precision-engineered in Japan to deliver exceptional vertical radiation efficiency and long-range wireless infrastructure. Operating across the 144–146 MHz (VHF) and 430–440 MHz (UHF) frequency spectrums, this heavy-duty omnidirectional antenna features a rugged, weatherproof white fiberglass radome that seals the internal silver-plated radiator elements against moisture ingress and atmospheric degradation. It stands as an essential physical infrastructure asset for professional repeater sites, corporate base stations, emergency response command centers, and high-rotation B2B radiocommunication distribution networks.
The advanced internal electromagnetic layout utilizes a high-efficiency 6/8-wave phased element configuration on VHF to deliver a steady 4.5 dB gain, alongside a high-torque 3 x 5/8-wave stacked collinear architecture on UHF that achieves a powerful 7.2 dB gain profile. This specialized engineering focuses the radiation pattern tightly toward the horizon, minimizing signal waste and maximizing coverage loops. Built to sustain severe environmental exposure, the antenna handles a massive 200-Watt peak power threshold and boasts an industrial wind velocity rating of up to 60 meters per second. Terminated with a premium, low-loss N-Female (N-J) connector bulkhead, it comes complete with heavy-duty aluminum mounting brackets designed to clamp securely onto standard masts ranging from 30 mm to 62 mm in diameter.
