The Moonraker MAG-270S is a professional-grade, high-integrity dual-band mobile antenna system precision-engineered to provide immediate, reliable communication profiles across the primary VHF and UHF amateur radio bands. Operating seamlessly over the 144–149 MHz (2M) and 430–450 MHz (70CM) frequency spectrums, this turnkey magnetic mount setup is an ideal choice for emergency coordination setups, tactical field deployments, and mobile fleet vehicle staging. It serves as an essential infrastructure asset for radiocommunication logistics, search and rescue units, and B2B hardware distribution networks looking to source original pre-tuned mobile hardware packages.
The advanced internal RF architecture functions as a precision-matched multi-band radiating element, configured electrically as a highly efficient 1/4 wave radiator on the 2-meter band and a 5/8 wave array on the 70-centimeter band. Arriving fully pre-tuned from the factory, the MAG-270S drops the need for complex field adjustments or optimization loops, delivering a forward signal gain profile of 3.0dBd on the UHF band. At its resonant center points, the antenna maintains a voltage standing wave ratio (VSWR) calibration of 1.5:1 or better, perfectly stabilizing impedance paths to safeguard your mobile transceiver’s final power amplifier stages from destructive reverse-power reflections.
Built as a complete all-in-one vehicular installation solution, the compact hardware profile has a vertical vertical clearance length of 50cm, minimizing structural stress and wind drag during highway transits. The antenna element interfaces directly with a heavy-duty magnetic base via a secure SO-239 bulkhead fitting. To shield the vehicle’s paintwork from scratches and metal-on-metal abrasion during heavy multi-shift operations, the magnetic housing is wrapped in a durable, protective rubber boot layer that dampens chassis micro-vibrations smoothly.
Equipped for immediate drop-in integration, the magnetic mount base features a pre-wired, high-grade 4-meter RG58 coaxial feedline cable. The flexible, low-loss line provides ample headroom for clean routing underneath interior cabin trim from the vehicle’s roof panel straight to the transceiver console. Pre-terminated in a standard low-loss male PL-259 plug connector, this turnkey dual-band assembly handles a steady transmission power capacity up to 50 Watts, providing robust, field-ready out-of-the-box readiness for your technical hardware fleet.
