The AC8-725HP is a high-performance, high-power UHF collinear antenna designed for the 700–750 MHz band. Housed in a ruggedized fiberglass radome, this antenna is engineered for mission-critical base station applications where extreme power handling and omni-directional reliability are non-negotiable. With its 1 kW continuous power rating, it is one of the most robust collinear solutions available for the 700 MHz spectrum.
Performance, Durability, and Efficiency
High-Power Engineering
The standout feature of the AC8-725HP is its 1000 Watt (1 kW) power handling capacity. To achieve this, the antenna utilizes an air-cored transmission line rather than standard polyethylene or foam dielectrics, which can melt or degrade under high thermal stress. All internal junctions are fully welded and clamped to prevent RF inter-modulation and ensure structural integrity at peak power levels.
Precision Radiation Pattern
The antenna features a center-fed design, a critical engineering choice that eliminates pattern distortion and ensures a true omni-directional horizontal pattern. By stacking large-diameter brass radiating elements vertically and feeding them in phase, the antenna achieves a concentrated 12-degree vertical beam-width, focusing energy toward the horizon for maximum signal reach without the need for field tuning.
Structural Hardening
Designed for the "worst-case" environments, the internal brass and aluminum components are completely encased in a high-tech ruggedized fiberglass radome. This enclosure protects the array from ice, wind, and corrosive pollutants while maintaining a 200 Km/Hr wind rating. The antenna termination is strategically located at the bottom to provide complete weather protection.
