| AC12-650 | High Gain Fiber Glass Collinear Antenna | 600–700MHz | 12 dBi |  |  |  |
The AC12-650 is a strategic-grade UHF fiberglass omnidirectional collinear antenna engineered for the 600–700 MHz spectrum. Featuring a massive 5.0-meter (16.4-foot) aperture, it delivers an elite 10 dBd (12 dBi) gain. This antenna is designed for high-density radio sites and long-haul terrestrial links where extreme signal focus and structural resilience are paramount.
Elite Omnidirectional Reach
The AC12-650 represents the pinnacle of collinear engineering, offering a razor-sharp 7-degree vertical beam-width. By concentrating RF energy toward the horizon with such high precision, the antenna maximizes regional reach and signal penetration. The center-fed design is a critical feature that eliminates the pattern distortion common in base-fed antennas, ensuring a consistent, true 360 degrees horizontal footprint.
Strategic Structural Hardening
Constructed from 6063T6 ultra-corrosion-resistant aluminum and high-class brass alloys, this antenna is built to endure the most hostile environments. All internal junctions are fully welded to prevent passive inter-modulation (PIM), ensuring a clean signal even at highly populated radio sites. The internal elements are housed in a high-tech ruggedized fiberglass radome, providing excellent RF transparency and enough structural integrity to withstand 200 Km/Hr winds.
Operational and Logistical Efficiency
Despite its overall length of 5.0 meters, the AC12-650 is designed for logistical ease, featuring a shipping length of 2.6 meters. This sectional approach allows for easier transport to remote tower sites. The antenna comes factory-tuned with special stub matching to ensure a VSWR of better than 1.5:1 across a 40 MHz bandwidth, requiring no complex field adjustments. It is finished in a military Olive Green color, ideal for tactical concealment.
| Feature | Specification | Tactical Benefit |
