The Sirio N-PL antenna mount is a commercial-grade vehicular installation base engineered to deliver a highly durable, low-loss RF connection for mobile vertical transceivers. Precision-manufactured to sustain rigid body integration, this heavy-duty hole-mount base is optimized for high-performance communication systems operating across a wide frequency range from 0 to 300 MHz. It provides an ideal mechanical anchor for Citizen Band (27 MHz CB) radio equipment, 10-meter amateur radio arrays, and generic low-power VHF/UHF configurations, making it a critical utility asset for fleet maintenance benches, public safety logistics, transport networks, and high-volume B2B radiocommunication accessory wholesale distribution channels across European markets.
The physical engineering framework centers around a compact 40 mm base diameter designed for permanent, non-destructive mechanical integration into a Ø 12.5 mm drilling hole on the vehicle’s roof, trunk, or boot panel. Outfitted with a standard, premium-machined PL Female (SO-239 style) antenna connector, the mount establishes a solid, vibration-proof electrical bond with any mobile antenna equipped with a corresponding PL-259 (UHF-Male) interface. To prevent contact degradation and safeguard the internal threads against water ingress, dirt, and corrosion during periods when the radiating whip element is uninstalled, the system includes a dedicated heavy-duty threaded protective cap. Weighing an ultra-lightweight 65 grams, its low-profile black styling guarantees a clean, professional, and aerodynamic integration onto any commercial vehicle chassis.
