AWD-100-2000

The AWD-100-2000 is a professional-grade, ultra-wideband discone antenna designed for consistent 360-degree coverage across a massive frequency spectrum. By covering 100 MHz to 2000 MHz in a single aperture, it eliminates the need for multiple antennas, making it the premier choice for spectrum monitoring, tactical jamming, and multi-band base station applications.

Advanced Design and Performance

The AWD-100-2000 is a vertically polarized omnidirectional discone antenna engineered for true broadband performance. It maintains a low VSWR across its entire operating range, allowing it to function with high efficiency as both a transmitting and receiving antenna. With a typical gain of 2 dBi and a broad vertical beam-width of 78 degrees, it provides excellent hemispherical coverage, ensuring that signals are captured or transmitted effectively regardless of the elevation of the communicating station.

Rugged Construction and Durability

Designed for all-weather survivability, the antenna is constructed from 6063T6 architectural-grade anodized aluminum alloy. The hubs and elements are finished with a Military Olive Green powder coating, providing a ruggedized shield against UV radiation and chemical exposure. To ensure long-term mechanical integrity, all fasteners are made of marine-grade stainless steel, and the insulators utilize high-performance Teflon and Nylon. The internal feed cable and N-Female termination are enclosed within the mounting pipe, offering complete protection against moisture and the elements.

Operational Efficiency and Logistics

The AWD-100-2000 is a "fit-and-forget" model that requires no field tuning or adjustments. For logistical efficiency, the disc and cone elements are removable, allowing the antenna to be packed into a compact 1.0-meter shipping container. Despite its rugged build, the unit weighs only 5.5 Kgs, facilitating fast and easy installation by a single technician. Its aerodynamic profile allows it to survive extreme wind speeds of up to 200 Km/Hr, making it suitable for high-altitude peaks or exposed coastal sites.

Detailed Technical Features

• Ultra-Wideband Frequency Response: Provides continuous, high-efficiency operation from 100 MHz to 2000 MHz, covering VHF, UHF, and L-Band frequencies in a single aperture.
• Constant 360° Omnidirectional Coverage: Engineered to maintain a uniform horizontal radiation pattern, ensuring seamless signal acquisition and transmission from all directions without "dead zones."
• High Power Transmission Capacity: Capable of handling up to 500 Watts of RF power, making it ideal for high-intensity Electronic Countermeasures (ECM) and jamming applications.
• Optimized Vertical Beam-width: Features a broad 78-degree half-power vertical beam-width, which provides excellent hemispherical coverage and prevents signal loss during high-angle ground-to-air or mountainous communication.
• Linear Vertical Polarization: Designed to match the standard polarization of tactical handhelds, mobile radios, and airborne systems for maximum link stability.
• Superior Impedance Matching: Maintains a VSWR of better than 2.5:1 across the entire 1.9 GHz bandwidth, ensuring minimal reflected power and protecting sensitive transmitter hardware.
• Passive Architecture: A completely passive design that requires no field tuning, adjustments, or power supply, ensuring 100% reliability in remote or hostile environments.
• Frequency Consolidation: Eliminates the logistical and visual burden of deploying multiple antennas by consolidating multi-band requirements into one rugged unit.
• High Sensitivity for Monitoring: Designed with low internal noise characteristics, making it highly effective for wide-spectrum ELINT (Electronic Intelligence) and SIGINT (Signal Intelligence) missions.

Technical Summary Table

Key Advantages

• Frequency Agility (100–2000 MHz): The primary advantage is the massive, continuous bandwidth. It covers VHF, UHF, and L-Band frequencies without the need for frequency-specific switching or hardware changes.
• Omnidirectional Hemispherical Coverage: With a 360° horizontal pattern and a broad 78° vertical beam-width, the antenna provides "bubble" coverage. This ensures that signals from ground-based units and aerial platforms are captured simultaneously.
• High Power Burn-Through: Capable of handling 500 Watts, it allows for the use of high-power amplifiers to "burn through" interference or provide high-intensity jamming coverage across a wide area.
• Zero Field Maintenance: The antenna is a passive, pre-tuned device. It requires no field tuning or electrical adjustments, making it a "fit and forget" solution for remote or unmanned stations.
• Integrated Weather Protection: The RF termination and feed cable are housed inside the mounting pipe. This protects the most vulnerable parts of the system from moisture, ice, and salt-fog degradation.

Strategic Benefits

• Logistical Simplification: Since one antenna covers 1.9 GHz of bandwidth, the logistics of shipping, storing, and deploying multiple antenna types are eliminated.
• Reduced Mast Loading: Using a single AWD-100-2000 reduces the weight and "wind-sail" surface area on a tactical mast. This allows for the use of lighter, more portable masts or increases the stability of fixed towers in high winds (up to 200 Km/Hr).
• Low Visual & RF Signature: A single antenna is harder to detect visually and via radar than a complex multi-antenna array, providing a "low-profile" benefit to tactical command posts.
• Protection of Radio Hardware: The D.C. Grounded design and excellent VSWR (<2.5:1) ensure that reflected power is minimized and static electricity is bled off, significantly extending the life of connected high-value radio equipment.

Primary Applications

1. Spectrum Monitoring & SIGINT: Ideal for Signal Intelligence (SIGINT) and Electronic Intelligence (ELINT) units that need to monitor a massive range of frequencies simultaneously to detect enemy transmissions or civilian broadcast activity.

2. Tactical Jamming & Electronic Warfare (EW): The 500W power rating makes it a premier choice for wide-spectrum jamming. It can be used to disrupt enemy radio communications, cellular signals, and remote-controlled improvised explosive devices (RCIEDs).

3. Ground-to-Air (UHF/VHF) Base Stations: Its broad vertical beam-width makes it perfect for air traffic control (ATC) or military ground-to-air links, maintaining a stable connection even as aircraft pass directly overhead or at steep angles.

4. C4I Multi-Band Command Hubs: In a command-and-control center where various radio types (FM tactical, digital trunked, and L-band data) are in use, the AWD-100-2000 acts as a universal hub, consolidating all communications into a single mast position.

5. Urban Security & Public Safety: Used by emergency services and urban security forces to provide wide-area coverage for multi-agency interoperability, ensuring that different radio systems can all communicate through a central relay point.

MIL-STD Compliance (Military Standards)

The antenna is designed to withstand the "Rough Handling" and "Extreme Environment" protocols defined by MIL-STD-810G:

• Low Temperature (Method 502.5): Operational and storage tested from -40°C to +80°C. The use of Teflon and Nylon insulators ensures no material embrittlement or cracking in arctic conditions.
• High Temperature (Method 501.5): The 6063T6 aluminum alloy and powder-coated finish prevent structural warping and heat-soak degradation in desert environments.
• Salt Fog (Method 509.5): All fasteners are Type 316 Marine Grade Stainless Steel, and the body is anodized/powder-coated to prevent galvanic corrosion during prolonged exposure in coastal or naval environments.
• Rain & Humidity (Method 506.5 / 507.5): The internal termination design (N-Female connector housed inside the support pipe) ensures zero water ingress into the RF path during high-velocity blown rain.
• Shock & Vibration (Method 516.6 / 514.6): Ruggedized for transport in tactical ground vehicles and operation on high-vibration platforms like naval vessels or armored command centers.

European Union (EU) Standards
