| AC9-650 | High Gain Fiber Glass Collinear Antenna | 614–698MHz | 9 dBi. |  |  |  |
The AC9-650 is a professional-grade UHF fiberglass omnidirectional collinear antenna engineered for the 614–698 MHz band. This ruggedized model combines high-class brass radiating elements with a center-fed design to provide a true $360^{\circ}$ horizontal radiation pattern. With full MIL-STD-810G environmental hardening, it is specifically designed for tactical and fixed-station applications in the most demanding operational theaters.
Precision Omnidirectional Coverage
The AC9-650 utilizes a center-fed design, a critical architectural choice that eliminates pattern distortion often found in base-fed models. This ensures a consistent, circular horizontal pattern. By stacking large-diameter brass elements vertically and feeding them in phase, the antenna achieves a 9 dBi gain with an 18-degree vertical beam-width, focusing energy toward the horizon to maximize range.
Tactical Structural Hardening
The antenna is encased in a high-tech, ruggedized fiberglass radome that provides excellent RF transparency while protecting internal components from extreme mechanical and environmental stress. All internal junctions are fully welded to prevent passive inter-modulation (PIM), ensuring signal purity. The assembly is finished in army olive green, making it ideal for tactical concealment and military infrastructure.
MIL-SPEC Environmental Resilience
This model is fully compliant with MIL-STD-810G standards. It is built to survive high-intensity shock, vibration, and extreme thermal windows. Specialized coatings and sealing provide total resistance against salt fog, fungus, and driving rain, ensuring that electrical performance remains stable in coastal, jungle, or industrial environments.
