The Diamond VX-30 dual fiberglass band antenna is a commercial-grade, short-profile base station vertical radiator precision-engineered to deliver high-efficiency multi-band communications across very high frequency (VHF) and ultra-high frequency (UHF) spectrums. Constructed inside a heavy-duty, weather-shielded fiberglass radome, this premium antenna is designed with a highly advanced radial-free structure (has no radials), making it an exceptional footprint alternative for tight residential balconies, crowded utility towers, or low-clearance maritime hulls. It serves as an essential logistics procurement asset for emergency operations coordination centers, localized municipal dispatch lines, high-reliability commercial repeaters, and high-volume B2B radiocommunication hardware wholesale networks looking to secure premium Diamond base infrastructure.
The internal electrical engineering of the Diamond VX-30 utilizes high-stability phasing elements calibrated to deliver sharp, low-angle radiation patterns for excellent line-of-sight propagation fields without a surrounding physical ground plane. The vertical array yields a solid power gain of 2.15 dBi in the VHF band (144 MHz) and an impressive 5.5 dBi in the UHF band (430 MHz), functioning natively as a 1/2 wave on VHF and a two-element 5/8 wave architecture on UHF. Engineered to comfortably manage heavy duty cycles from high-output base station amplifiers, the internal network safely handles a maximum power rating of 150 Watts PEP while keeping a tight, uniform voltage standing wave ratio (V.S.W.R. of 1.5 or better) across standard 50 Ohms characteristic impedance lines.
Standing at a compact total structural length of exactly 1.30 m and carrying a net component mass of just 0.75 kg, the light, aerodynamic profile minimizes mechanical twisting torque on masts, showing a certified physical wind resistance of up to 60 m / sec. (over 215 km/h). To guarantee a smooth, immediate installation out of the box, the factory packaging completely includes heavy-duty brackets and structural clamps for fastening the base securely to an active support mast. Delivered completely turnkey, this dual-band vertical array ensures immediate technical system alignment, tool-free field setup, and absolute multi-shift deployment readiness.
