| AC9-550 | High Gain Fiber Glass Collinear Antenna | 512–608MHz. | 9 dBi. |  |  |  |
The AC9-550 is a professional-grade UHF fiberglass omnidirectional collinear antenna engineered for the 512–608 MHz band. This ruggedized model combines high-class brass radiating elements with a specialized center-fed architecture to provide a true 360 degrees horizontal radiation pattern. Designed for survivability in extreme environments, it serves as a high-gain backbone for tactical communications and fixed-station infrastructure.
Precision Omnidirectional Coverage
The AC9-550 utilizes a center-fed design, a critical engineering choice that eliminates the pattern distortion often found in base-fed collinear antennas. This ensures a consistent, circular horizontal signal footprint. By stacking large-diameter brass elements vertically and feeding them in phase, the antenna achieves a 9 dBi gain with a concentrated 12-degree vertical beam-width, focusing energy toward the horizon for maximum regional reach.
Strategic Structural Hardening
The antenna is encased in a high-tech, ruggedized fiberglass radome that offers excellent RF transparency while providing the structural integrity required to withstand 200 Km/Hr winds. All internal junctions are fully welded to prevent passive inter-modulation (PIM), ensuring long-term signal purity. The assembly is finished in military Olive Green, making it ideal for tactical concealment and defense applications.
Maintenance-Free Reliability
Designed for "set-and-forget" operation, the AC9-550 requires no field tuning or adjustments. Factory-optimized stub matching ensures a smooth VSWR of better than 2.0:1 across the entire 512–608 MHz bandwidth. The internal brass radiating elements are protected from oxidation and environmental degradation, ensuring consistent electrical performance over a long service life.
