The Jetfon A-400 UHF base station antenna is a commercial-grade, heavy-duty vertical radiation element engineered to deliver outstanding omnidirectional coverage and reliable long-range link tracking across the professional Ultra High Frequency spectrum. Constructed from premium, weather-resistant stainless steel elements paired with a ruggedized aluminum fixation base, this high-performance antenna measures a commanding maximum physical footprint length of 520 cm. Outfitted with a specialized three-radial ground plane architectural typology, this configuration compresses vertical radiation angles toward the horizon, making it an essential infrastructure procurement asset for municipal dispatch hubs, commercial security networks, private wireless links, and high-volume B2B radiocommunication distribution channels across European markets.
The precise electrical engineering of the Jetfon A-400 features a highly versatile operating bandwidth spanning the 400 MHz to 470 MHz spectrum. Accompanied by an official factory field-tuning cutting board diagram, installation technicians can easily trim the 1/4 wave elements to achieve an exact resonant frequency match for maximized transceiver protection and clean signal propagation. Engineered to manage continuous power thresholds up to a 100 Watts maximum power rating with a nominal system impedance, it yields a powerful 9 dB signal gain metric to pierce through dense terrain and complex urban obstacles. Terminated in a high-integrity, chassis-mounted SO-239 (PL Female) connector interface at the base, it ensures an absolute mechanical bond and immediate fleet deployment readiness.
