The Diamond HC200 SJ premium UHF portable antenna is a commercial-grade, field-tunable radiation element engineered to deliver outstanding close-to-mid-range link tracking and exceptional structural versatility for handheld transceivers. Measuring a highly compact maximum physical length profile of 0.20 meters (20 cm) and weighing an ultra-lightweight 27 grams, this high-performance whip features a flexible, sleek structural polymer shroud built to handle rigorous field operations. Equipped with an integrated technical cutaway diagram (trim chart), this specialized antenna allows technicians to precisely cut the radiating element to optimize resonance across a wide 350 MHz to 520 MHz UHF frequency range, making it an essential operational procurement asset for localized industrial facilities, private security grids, tactical field coordinates, and high-volume B2B radiocommunication accessory wholesale networks across European markets.
The advanced internal electrical architecture of the Diamond HC200 SJ functions as a high-efficiency 1/4λ (quarter-wave) wavelength typology when tuned to the primary transmission bands, yielding a stable 2.15 dBi radiation gain metric. The engineered electrical framework is built to safely handle continuous power thresholds up to a 10 Watts maximum power rating across a nominal 50-Ohm characteristic system impedance, all while maintaining a strict, equipment-protecting VSWR of less than 1.5:1. Terminated at its heavy-duty base assembly with a low-profile SMA-Female (SJ typology) interface connector, it ensures a secure, vibration-resistant mechanical bond with compatible portable devices, allowing communications managers to achieve immediate technical system alignment and absolute fleet operational readiness.
