AG-50

Overview: AG-50 High-Gain Ground Plane Antenna

The AG-50 is a rugged, military-grade High-Gain Ground Plane Antenna designed for the low-band VHF spectrum (30–66 MHz). Engineered for high efficiency and structural durability, this antenna is an ideal choice for tactical base stations, field headquarters, and long-range VHF communication links. By utilizing ultra-corrosion-resistant architectural aluminum and a high-power handling design, the AG-50 provides a stable 360-degree signal "bubble" capable of sustaining critical communications in the most punishing environmental conditions.

Tactical Construction & Engineering

Hardened materials for zero-failure field performance. The AG-50 is constructed from 6063T6 architectural aluminum alloy, known for its superior strength-to-weight ratio and corrosion resistance. To ensure long-term reliability, all mounting hardware and fasteners are fabricated from marine-grade stainless steel. A key technical advantage of the AG-50 is its all-aluminum construction, which prevents the formation of "Signal Cells," effectively eliminating internal inter-modulation—a critical factor when operating high-power transmitters up to 500 Watts.

Operational Efficiency

True omni-directional dominance with maximum weather shielding. The AG-50 delivers a stable 2.15 dBi gain and an exceptional VSWR of better than 1.5:1 over its specified 4% bandwidth. Its wide 78-degree vertical beamwidth ensures consistent "null fill," providing reliable signal saturation for ground-level units and assets at varying elevations. For maximum longevity, the N-Female termination and feed cable are fully enclosed within the mounting pipe, shielding the most vulnerable electrical connections from moisture, ice, and mechanical stress.

Detailed Technical Features

• Low-Band VHF Mastery: Optimized for the 30–66 MHz range, providing the long-range propagation characteristics essential for tactical military communication.
• High Power Handling: Engineered to handle a sustained 500 Watts of RF power, making it a robust choice for tactical broadcasting and area denial.
• Inter-Modulation (IM) Suppression: All-aluminum architecture eliminates internal diode effects, ensuring a clean noise floor during transmission.
• True Omni-Directional Pattern: Provides 360-degree horizontal coverage for uniform localized network distribution.
• Superior Null Fill: The wide 78° vertical beamwidth eliminates "dead zones" at close range, ensuring constant connectivity for nearby units.
• Internalized Feed Protection: Cable termination is housed inside the support pipe, providing 100% weather protection for critical RF connections.
• Rapid Field Assembly: Designed to be assembled with simple hand tools; ground radials are removable for compact 1.6-meter shipping lengths.
• Universal Mount: Suitable for standard 38–51 mm (1.5–2 inch) outer diameter round pipes.

Environmental Specifications

The AG-50 is built to survive extreme theater conditions:

• Operating Temperature: Certified for mission-critical use from -30°C to +70°C.
• Storage Resilience: Safe for non-operational storage in temperatures from -40°C to +80°C.
• Humidity Defense: Fully functional in 0 to 95% Relative Humidity, ideal for tropical or coastal environments.
• High-Velocity Wind Rating: Aerodynamically optimized to survive constant winds up to 185 Km/Hr.

Key Advantages, Benefits & Applications

Key Advantages:

• Signal Purity: The "Signal Cell" prevention design ensures high-fidelity audio and data transmission even at maximum power.
• Corrosion Immunity: 6063T6 aluminum and stainless steel hardware ensure the antenna remains rust-free in saline or humid atmospheres.
• Ease of Logistics: Removable radial design significantly reduces the transport footprint for rapid-response tactical units.

Key Applications:

• Tactical VHF Base Stations: Primary communications link for field headquarters and remote outposts.
• Military Search & Rescue: Reliable wide-area coverage for coordination in rugged, off-grid terrain.
• Electronic Warfare (EW): Serving as a high-power source for low-band VHF jamming and signal denial.
• Public Safety Networks: Providing durable infrastructure for emergency services operating in the 30–66 MHz band.
