Description
The D2218-A is a rugged, military-grade omni-directional dipole antenna, designed for mission-critical ground-to-air communications in military, defense, and FAA-regulated air traffic control operations. Featuring a modular two-piece sectional design, it provides enhanced portability and simplified deployment, making it ideal for tactical operations, transport-sensitive applications, and temporary installations.
Engineered for simultaneous multi-band operation, the D2218-A integrates three independent dipoles within a single enclosure, delivering two VHF outputs (116-150 MHz) and one UHF output (225-400 MHz) while maintaining high isolation for interference-free, multi-frequency connectivity. With 360-degree omnidirectional coverage, it ensures secure, uninterrupted communication between ground stations and aircraft, optimizing signal clarity and efficiency for defense forces, military aviation, and critical air traffic control networks. Built to military specifications, its rugged, all-weather construction guarantees long-term durability and high-performance transmission in extreme conditions.
