| AC6-350 | UHF High Gain Fiber Glass Collinear | 300-400MHz | 6 dBi. |  |  |  |
The AC6-350 is a professional-grade UHF fiberglass omnidirectional collinear antenna engineered for the 300–400 MHz spectrum. Designed for tactical and fixed-station applications, this ruggedized model provides a balanced 6 dBi gain with a wide 20-degree vertical beam-width, ensuring reliable regional coverage across varying terrains.
Precision Omnidirectional Coverage
The AC6-350 utilizes a center-fed architecture, a critical engineering choice that eliminates the pattern "tilt" or distortion often found in base-fed collinear antennas. This ensures a true, perfectly circular 360 degrees horizontal signal footprint. The internal array consists of vertically stacked, large-diameter brass elements fed in phase, focusing RF energy toward the horizon for maximum regional link stability.
Tactical Structural Hardening
Constructed from high-class brass and 6063T6 ultra-corrosion-resistant architectural aluminum, the antenna is built for long-term survival in hostile environments. All internal junctions are fully welded to prevent passive inter-modulation (PIM), ensuring a clean signal even at sites with high RF density. The entire internal array is protected within a high-tech ruggedized fiberglass radome, which is RF-transparent and strong enough to withstand wind loads up to 200 Km/Hr.
Maintenance-Free Reliability
The AC6-350 requires no field tuning or adjustments. Factory-optimized stub matching ensures a smooth VSWR of better than 1.5:1 across its 20 MHz bandwidth. The antenna termination is enclosed at the bottom for total weather protection, and the standard military Olive Green finish provides tactical concealment, making it ideal for defense and secure government infrastructure.
| Feature | Specification | Tactical Benefit |

| Gain | 6 dBi | Balanced reach for regional omni coverage. |
| Vertical Beam | 20 Degrees | Wide vertical aperture for varying terrain. |
| Wind Rating | 200 Km/Hr | Stays operational in hurricane-force conditions. |
| Weight | 3 Kgs | Ideal for rapid-deployment and mobile masts. |
