The AC3-312 is a military-grade, UHF Aviation Band Omni-Directional Antenna engineered for the 225–400 MHz tactical spectrum. This ruggedized aperture is specifically designed for high-reliability Air Traffic Control (ATC) sites, ground-to-air coordination, and shipboard communication. By utilizing a specialized "Choke and Spark Gap" technique, the AC3-312 ensures a smooth VSWR and constant 3 dBi gain across the entire band, providing consistent 360-degree situational awareness in a compact, weather-shielded form factor.
Design: High-Fidelity Aero-Band Communication
The AC3-312 is optimized for mission-critical hubs requiring stable signal propagation to high-elevation assets and long-range ground transceivers. Its internal architecture features high suppression of skin current, which prevents pattern distortion and maintains a smooth VSWR of better than 2:1. The wide 78-degree vertical beamwidth is precision-tuned for aeronautical applications, ensuring that air traffic controllers and tactical units maintain a rock-solid link with aircraft from the horizon to nearly overhead.
Construction: MIL-SPEC Hardening & Maritime Resilience
Built to survive 24/7 exposure in the world’s most punishing environmental theaters, the AC3-312 utilizes 6063T6 ultra-corrosion resistant architectural aluminum alloy. The radiating elements are fully enclosed within a high-tech ABS radome, which provides excellent RF transparency while protecting against UV radiation, acid rain, and heavy ice formation. All assembly hardware is crafted from Type 316 marine-grade stainless steel, and the antenna is finished with an epoxy-based Olive Green (RAL 6003) powder coating for maximum resistance to salt fog and corrosive gases.
Integration: Tactical Mobility & Shipboard Readiness
The AC3-312 is designed for seamless integration into fixed ATC sites, mobile command vehicles, and naval shipboard superstructures. At only 850 mm (33.5 inches) in length, it offers a compact physical profile with a low wind-loading coefficient (200 Km/Hr rating). The N-Female termination is fixed at the bottom of the mounting pipe, shielding the critical RF connection from moisture and mechanical stress. This sturdy, maintenance-free design allows for high-power transmission up to 500 Watts, supporting high-intensity secure voice and data links.

Advanced UHF Aviation Antenna: The AC3-312 is a rugged, high-performance omni-directional UHF aviation band antenna engineered for seamless ground-to-ground and ground-to-air military and ATC communication. Operating across the entire 225–400 MHz frequency band, this broadband antenna utilizes stacked, large-diameter radiating elements paired with a specialized "Impedance Matching" technique. This advanced engineering ensures high suppression of skin current, delivering an ultra-smooth VSWR and a constant 3 dBi gain without requiring any field tuning. Constructed from premium 6063T6 architectural aluminum alloy and supplied with marine-grade type 316 stainless steel mounting brackets, its ultra-corrosion-resistant build guarantees maximum structural integrity for fixed-station, shipboard, and mobile deployments. Ruggedized RF Protection: For ultimate survivability in extreme environments, the antenna is fully enclosed in a high-tech, UV-resistant ABS radome. This heavy-duty, cylindrical enclosure features exceptional RF transparency, low wind loading, and minimized ice-formation vulnerability, ensuring uninterrupted broadband performance under severe weather conditions. Designed with an integrated N-Female termination sealed at the bottom of the mounting pipe for absolute weatherproofing, the compact and aesthetically streamlined housing eliminates the need for multiple antennas. The AC3-312 comes standard in a military-spec olive green finish, with customizable housing colors available to meet specific tactical or aesthetic deployment requirements.
