The Diamond BC200 is a professional-grade, high-integrity UHF vertical base station antenna precision-engineered to deliver exceptional omnidirectional signal propagation and reliable wide-area tracking. Featuring an advanced 3×5/8 wave (3×5/8λ) architecture enclosed in a heavy-duty fiberglass (FRP) outershell radome, this premium fixed-station radiator is custom-built to replace standard metal whips that suffer from weather degradation or unstable grounding loops. It stands as an ideal infrastructure asset for commercial public safety systems, industrial plant facilities, and base depots requiring a durable, high-gain communication node.
The advanced internal RF architecture covers a broad operational frequency span from 430 to 490 MHz, making it highly versatile for commercial UHF land-mobile frequencies and amateur bands. To ensure absolute technical system alignment across your specific operating channel, the antenna includes an official factory tuning cut-off diagram, allowing technicians to precision-trim the internal radiating element to a perfect resonant center point. Once calibrated, the array maintains an ultra-efficient voltage standing wave ratio (VSWR) of less than 1.5:1, protecting your transmitter’s final stage circuits from destructive reverse-power reflections.
Built to endure severe environmental stress, the BC200 features an aerodynamic, heavy-duty fiberglass shell measuring 1.7m in length and weighing a balanced 900 g. The base is equipped with rugged ground-plane radials to stabilize the radiation pattern, yielding an impressive forward signal gain of 6.5dB. The entire assembly is structurally rated to withstand extreme wind velocities up to 60m/sec. Delivered with a universal mounting bracket kit that accepts standard mast diameters from 30 to 62φ, and terminating in a low-loss female MJ (UHF-type) connector block with a 50ohms nominal impedance, this turnkey base antenna ensures immediate field deployment readiness for your technical hardware fleets.
