| AC6-150 | VHF High Gain Fiber Glass Collinear | 136-174MHz | 6 dBi |  |  |  |
The AC6-150 is a professional-grade VHF fiberglass omnidirectional collinear antenna designed for the 136–174 MHz band. Featuring a balanced 6 dBi gain and a wide 36-degree vertical beam-width, this antenna is engineered for reliable medium-to-long haul regional coverage. With full MIL-STD-810G environmental hardening, it is an ideal solution for mission-critical base stations, repeaters, and tactical nodes in demanding operational theaters.
Precision Omnidirectional Coverage
The AC6-150 utilizes a center-fed design, a critical engineering choice that eliminates the pattern distortion and "beam tilt" often associated with base-fed collinear antennas. This ensures a perfectly circular 360 degrees horizontal radiation pattern. By stacking large-diameter brass elements vertically and feeding them in phase, the antenna maintains a stable signal footprint across its operational bandwidth.
Tactical Structural Hardening
Constructed from high-class brass and 6063T6 ultra-corrosion-resistant anodized aluminum alloy, the antenna is designed for maximum survival. All internal junctions are fully welded to prevent passive inter-modulation (PIM), ensuring signal purity even in RF-dense environments. The entire internal array is encased in a high-tech ruggedized fiberglass radome, which is RF-transparent and strong enough to withstand wind loads up to 200 Km/Hr.
MIL-SPEC Environmental Resilience
This model is fully hardened and tested to MIL-STD-810G standards. It is resistant to salt fog, fungus, heavy rain, and extreme thermal stress. Its mechanical integrity is verified through high-intensity shock and vibration testing, making it suitable for deployment in forward operating bases, coastal regions, or harsh industrial zones.
