The DIAMOND SD330 – Length:Approx. 1.85m \/ Weight:Approx. 1.1kg Frequency:3.5-30MHz \/ Max. power rating:200W (SSB) Impedance: 50\u03a9 \/ SWR:Less than 2.0 Connector:M-P \/ Type:1\/4 wave center loading Power supply voltage & current:DC 12V 100mA Up-down time:aprrox. 50 sec.(3.5\u219230MHz), aprrox. 20 sec. (7\u219230MHz)<\/strong> is a commercial-grade, motorized variable-frequency HF mobile station antenna precision-engineered to deliver secure voice synchronization, flexible multi-band spectrum tracking, and robust deployment readiness across active transport networks. Manufactured by Diamond Antenna, an international standard in elite RF hardware, this high-integrity center-loaded whip overhauls restrictive legacy single-band hardware setups. By integrating an internal remote-controlled motor drive to adjust resonance instantly across changing target zones, it serves as an essential operational procurement asset for tactical emergency response units, maritime transport fleets, cross-border field communication teams, and high-volume B2B radiocommunication hardware wholesale distribution networks looking to source original factory-genuine active mobile antenna components.<\/p>\n

The advanced internal RF architecture of the SD330 centers around an adjustable type: 1\/4 wave center loading<\/strong> core design, engineered to achieve broad-spectrum agility across a continuous global frequency: 3.5-30MHz<\/strong> matrix (covering the 80-meter through 10-meter amateur bands). Built to seamlessly support high-tier vehicular transceivers running structural field campaigns, the loading coil accommodates a max. power rating: 200W (SSB)<\/strong> peak envelope power. This motorized configuration utilizes an internal drive module running on a minor operational power supply voltage & current: DC 12V 100mA<\/strong> link, driving a mechanical lift that shifts the coil position to optimize matching efficiency. This system ensures swift band transit tracking, clocking an up-down time: approx. 50 sec. (3.5\u219230MHz)<\/strong> for full-spectrum shifting and a rapid approx. 20 sec. (7\u219230MHz)<\/strong> loop for standard high-frequency transitions.<\/p>\n

Housed inside a weatherized, high-durability structural body measuring an assembled length: approx. 1.85m<\/strong> and registering a well-balanced net weight: approx. 1.1kg<\/strong>, the antenna configuration applies minimal vertical physical leverage to automotive mounts. Tuned to interface cleanly with standard transmission cabling layouts along a system impedance: 50\u03a9<\/strong> path with a reliable matched SWR: less than 2.0<\/strong>, the feedpoint terminates in a standardized high-retention connector: M-P<\/strong> (PL259 UHF Male style) with an integrated heavy-duty threaded locking collar to protect lines from moisture ingress and intermittent signal drops. Delivered as a complete turnkey mobile solution requiring no manual whip manipulation on the road, this motorized antenna system delivers immediate technical compliance and absolute out-of-the-box field deployment readiness.<\/p>\n
