The AC9-850 is a professional-grade UHF fiberglass omnidirectional collinear antenna engineered for the 800–990 MHz spectrum. This high-gain model is designed for broadband applications, offering a substantial 90 MHz bandwidth suitable for GSM, trunking, and tactical communication links. Housed in a ruggedized radome with a center-fed design, it ensures high-reliability performance in extreme environmental conditions.

Precision High-Frequency Coverage

The AC9-850 utilizes vertically stacked, large-diameter brass radiating elements fed in phase to achieve a robust 9 dBi gain. Its center-fed architecture is a critical design feature; unlike base-fed antennas that often suffer from pattern distortion (beam tilt), this design ensures a true, symmetrical 360 degrees horizontal footprint. With a concentrated 12-degree vertical beam-width, the antenna focuses RF energy toward the horizon, providing exceptional long-range reach for regional base stations.

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 stress. All internal junctions are fully welded to prevent passive inter-modulation (PIM), ensuring a clean signal in RF-dense environments. The standard finish is military Olive Green, making it ideal for tactical concealment and secure defense infrastructure.

Maintenance-Free Reliability

Designed for "set-and-forget" operation, the AC9-850 requires no field tuning or adjustments. Factory-optimized stub matching ensures a smooth VSWR of better than 1.5:1 across its wide operating band. The termination is protected at the bottom of the structure for total weather protection, while marine-grade stainless steel mounting hardware prevents corrosion in saline or high-humidity environments.
