The PNI Duplex 2000 Mobile antenna CB-FM<\/strong> is a commercial-grade, multi-band automotive vehicular radiator precision-engineered to combine the technical characteristics of the license-free CB frequency (27 MHz) with those of standard car FM radio (88 – 108 MHz)<\/strong> into a single, high-efficiency mechanical housing. Designed as an elegant, low-profile replacement solution, this specialized transceiver mast seamlessly replaces the car’s original FM radio antenna, enabling vehicle operators to listen to broadcast radio entertainment while simultaneously transmitting and receiving voice communications over local Citizen Band channels. It serves as an essential logistics procurement component for commercial transport trucks, distribution vans, utility vehicle fleets, and high-volume B2B radiocommunication accessory wholesale distribution networks looking to optimize vehicle aesthetic profiles by eliminating multi-antenna clutter.<\/p>\n

The innovative architectural design of the PNI Duplex 2000 differs sharply from conventional installations by integrating an advanced internal isolation matrix that actively cancels local automotive electrical noise, ensuring pristine audio reception across both bands. To maintain maximum performance under diverse mounting geometries, the antenna features an adjustable tip<\/strong> that allows for quick, interference-free calibration. Under ideal installation and use conditions, the system delivers premium electrical matching parameters characterized by a minimum SWR in the center of the band of less than 1.2<\/strong>, an FM impedance of 150 Ohms<\/strong>, and a standard transmission CB impedance of 50 Ohms<\/strong> capable of handling a maximum applied power of 50 W<\/strong>.<\/p>\n

Built from heavy-duty, high-flexibility fiberglass<\/strong> material, the low-profile antenna body features a streamlined tip length of 440 mm<\/strong>, making it exceptionally resilient against impact strikes from low-hanging branches or clearance bar boundaries. The vertically polarized radiator is optimized to withstand extreme weather and operational climates, performing flawlessly across a broad operating temperature range of -26\u00b0C ~ +80\u00b0C<\/strong>. For a simplified layout and a clean installation routing path through automotive headliners, the kit includes 5 meters of premium low-profile RG174 cable<\/strong> splitting into dedicated leads terminated with a standard PL-259 connector for CB equipment<\/strong> and a parent ISO connector for standard automotive radio hubs<\/strong>. Requiring a fixed 16 mm installation hole diameter<\/strong>, this turnkey dual-purpose antenna ensures immediate technical system alignment and absolute fleet readiness.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n
