CD-100-156

The CD-100-156 is a heavy-duty, wideband coaxial dipole antenna designed for consistent omnidirectional performance across the 100–156 MHz range. Enclosed in a high-impact ABS radome, it is engineered to serve as a high-reliability link for Air Traffic Control (ATC), naval communication, and mobile command centers, covering both standard aviation and emergency VHF frequencies.

Stable Omnidirectional Performance

The CD-100-156 maintains a constant 2 dBi gain across its entire 56 MHz bandwidth. Utilizing a specialized "Choke and Spark Gap" technique, the antenna ensures superior radiation efficiency and pattern stability. Its 78-degree vertical beam-width provides broad hemispherical coverage, which is essential for maintaining a strong, uninterrupted signal with aircraft at varying altitudes while simultaneously communicating with ground or sea-based assets.

Professional Mechanical Hardening

Constructed for longevity in high-corrosion environments, the internal radiating elements are fabricated from 6063T6 architectural-grade aluminum alloy. These elements are completely sealed within a UV-resistant ABS radome, which protects the antenna from ice formation, abrasive sand, and chemical degradation. The cylindrical design is optimized for low wind loading, allowing it to sustain operation in severe weather with wind speeds up to 200 Km/Hr.

Operational and Tactical Efficiency

This "plug-and-play" solution requires no field tuning or adjustments, making it ideal for rapid-deployment forces. Electrical efficiency is enhanced by high suppression of skin current, which provides a smooth VSWR and minimizes noise. For maximum longevity, the N-Female termination is housed at the base of the mounting pipe, shielding the RF connection from moisture and environmental stress. The antenna is supplied with Type 316 marine-grade stainless steel hardware for zero-maintenance performance in maritime theaters.
