The premium Diamond WD330S Dipole antenna -Diamond WD330S is a 2-28.5 MHz, 10m long dipole antenna.<\/strong> is a commercial-grade, broadband HF tactical wire antenna precision-engineered to deliver secure voice synchronization, multi-frequency transmission tracking, and elite signal path conditioning across base station installations. Built utilizing a folded, terminated dipole architecture (T2FD style) to overhaul standard monoband wires that require mechanical antenna tuning units (ATUs) and experience continuous high SWR spikes when shifting frequencies, this premium high-compliance system stands as an essential operational procurement asset for permanent maritime shore bases, regional disaster emergency response centers, military command outposts, and high-volume B2B radiocommunication hardware wholesale distribution lines looking to source original factory-genuine active components.<\/p>\n

The advanced internal RF configuration of this high-integrity infrastructure node features unmatched frequency agility optimized for continuous resonance across an extensive HF spectrum block, tracking all **frequencies: 2 to 28.5 MHz** without operational gaps or localized blind zones. Loaded with a high-durability internal matching network, the system safely processes a **max. power rating: 150 W(PEP)** forward load limit. The broadband circuit configuration delivers an efficient horizontal radiation field, yielding a stable **VSWR: 2:1 from 2 to 18MHz** and **3:1 from 18 to 28.6MHz** curve baseline profile, which safeguards delicate transmitter final power amplifiers from destructive reverse-power thermal accumulation over wide frequency jumps.<\/p>\n

Constructed to survive punitive environmental placement coordinates and intense multi-season wind stress, the dipole assembly spans a highly compact physical **length: 10 m** wire footprint. This short spatial layout makes it exceptionally adaptable for tight roof spaces, courtyard masts, or urban balcony constraints where full-size wire arrays cannot clear structural obstacles. Weighing a balanced net structural **weight: 1.7 kg**, the complete kit includes rugged integrated spacer bars that prevent element line twists during severe storms. The feedpoint matches a standard system **impedance: 50 Ohms** transmission line path and terminates in a standardized high-retention **connector: PL (MP)** SO-239 female socket with heavy threaded locking mechanics. Delivered fully factory pre-assembled requiring zero manual field wire-cutting or tedious frequency tuning adjustments, this turnkey dipole antenna ensures absolute out-of-the-box field deployment readiness.<\/p>\n
