LP-20-3000L

The LP-20-3000L is an elite, military-grade Tactical MIL-STD Log Periodic Dipole Antenna (LPDA) designed for extreme wideband performance across the 20–3000 MHz spectrum. This directional powerhouse is engineered for rapid deployment in high-stakes environments, serving as a unified solution for high-power transmission, intercept, and electronic countermeasure (ECM) missions. By utilizing advanced loading techniques and a modular, foldable architecture, the LP-20-3000L balances immense frequency agility with tactical portability, making it a critical asset for modern signals intelligence (SIGINT) and electronic warfare (EW) theaters.

Design: Extreme Wideband Agility & Deployment Speed

The LP-20-3000L is optimized for mission-critical hubs that require immediate spectrum dominance from HF through the S-band.

• Full-Spectrum Coverage: Replaces the need for multiple antenna arrays by providing a single, continuous directional feed point for the entire 20–3000 MHz range.
• Rapid Tactical Setup: Engineered for high-mobility units, the antenna features foldable elements and a quick-connect stainless-steel stud system, allowing for a complete field assembly in less than 10 minutes.
• Size-Reduction Technology: Utilizes advanced loading techniques to reduce the overall physical footprint of the array without sacrificing gain or electrical efficiency, resulting in a manageable shipping length of just 3 meters.
• Polarization Flexibility: The mounting arrangement allows operators to switch between Horizontal and Vertical polarization in the field to match the intercepted signal or tactical network requirements.

Construction: Field-Hardened & Modular Durability

Built to withstand the world’s most punishing environmental theaters, from high-salinity coastal zones to high-intensity combat operations.

• Aerospace-Grade Materials: Constructed from 6063T6 ultra-corrosion resistant architectural anodized aluminum alloy. Support booms and elements are protected by an epoxy-based powder coating in Military Olive Green.
• Marine-Grade Hardware: All assembly fasteners, including screws, nuts, and bolts, are made of Type 316 marine-grade stainless steel for total immunity to corrosive gases and salt spray.
• Mechanical Integrity: Features extra spacers between support booms and a square-tube boom cross-section to ensure structural rigidity against 170 Km/Hr wind loads.
• D.C. Grounded Safety: Operates at D.C. ground with a low-resistance discharge path, providing inherent lightning protection and bleeding off static noise for high-fidelity signal interception.

Power Scaling: High-Power Version (LPHP-20-3000L)

For strategic signal denial and electronic attack (EA) missions, the antenna can be upgraded to the LPHP version. This high-power variant utilizes low-density PTFE (Teflon) dielectrics and tinned copper conductors with a fire-retardant FEP jacket.

• Strategic Throughput: Handles up to 5KW @ 50MHz, 1KW @ 1GHz, and 500W @ 3GHz.
• Termination Options: Supplied with DIN-Female or 1-5/8” EIA Female connectors to accommodate high-wattage tactical transmitters.

Key Advantages

• Ultimate Spectrum Dominance: Replaces an entire suite of antennas by covering the 20 MHz to 3000 MHz range with a single, high-performance feed point. This eliminates the logistical burden of transporting and swapping multiple antennas for VHF, UHF, and S-Band missions.
• Rapid Field Deployment: Engineered for high-mobility units, the foldable element design and quick-connect stainless-steel stud system allow for a complete field assembly in under 10 minutes, ensuring minimal time-to-signal in fast-moving tactical scenarios.
• High-Power Scalability: While the standard version handles 400W, the LPHP (High Power) option is a force multiplier, capable of managing up to 5KW, making it one of the few tactical LPDAs capable of high-intensity strategic jamming.
• Tactical Portability: Despite its 3-meter operational length, the two-section support boom and foldable architecture allow it to be collapsed into a 6-foot shipping length, making it ideal for transport in standard tactical vehicles or transit cases.
• Superior Directional Isolation: A 14 dB front-to-back ratio ensures that radiated energy is focused strictly on the target area while providing excellent protection for friendly communication systems and personnel located behind the antenna.
• Polarization Agility: The versatile mounting arrangement allows operators to switch between Horizontal and Vertical polarization in seconds, ensuring compatibility with any intercepted signal or tactical network architecture.
• Battlefield Survivability: Fully MIL-STD-810G compliant, with 6063T6 aluminum construction and marine-grade stainless steel hardware, it is built to survive extreme thermal cycles, high-velocity winds (170 Km/Hr), and corrosive salt-fog environments.

Key Applications

• Signals Intelligence (SIGINT): An elite tool for high-speed spectrum scanning and signal discovery. Its flat gain response allows for the detection of Low Probability of Intercept (LPI) signals across the entire tactical radio spectrum.
• Broadband Electronic Attack (EA): Primary platform for high-power wideband jamming. It is used to deny adversary tactical voice nets, data links, and modern high-frequency remote triggers across VHF/UHF/S-Bands.
• Direction Finding (DF): The precision directional pattern is essential for Line-of-Bearing (LOB) acquisition, allowing units to pinpoint the exact location of adversary emitters through triangulation.
• Tactical Communications Hub: Ideal for rapid-response Forward Operating Bases (FOBs) or Tactical Operations Centers (TOCs) that require a single, high-gain aperture for multi-band long-range communications.
• Spectrum Surveillance: Persistent monitoring of the electromagnetic environment in littoral or desert theaters, identifying new signals of interest while remaining immune to harsh environmental degradation.
• Counter-UAS (C-UAS): Directional disruption of drone command, control, and video telemetry links across the 2.4 GHz and other tactical microwave frequencies.

Strategic EW, SIGINT & Monitoring Compatibility: LP-20-3000L

The LP-20-3000L is a versatile, high-performance tactical asset designed for full-spectrum electromagnetic operations. Covering the massive 20–3000 MHz range (0.02 to 3.0 GHz) with a single directional aperture, it serves as a unified platform for Electronic Warfare (EW), Signals Intelligence (SIGINT), and persistent Spectrum Monitoring across the VHF, UHF, L-band, and S-band frequencies.

1. Electronic Warfare (EW) & Electronic Attack (EA)

In Electronic Attack missions, the LP-20-3000L acts as a Directional Power Projection Hub. Its architecture is specifically hardened for high-power, continuous-duty transmission.

• Broadband Signal Denial: Capable of jamming adversary tactical voice nets, high-speed data links, and modern RCIED triggers across a 2.98 GHz bandwidth.
• Strategic Power Scalability: While the standard version handles 400W, the LPHP high-power version can project up to 5KW, allowing for long-range, high-intensity suppression of enemy communications (SECOM).
• Focused Energy Projection: The directional pattern ensures that jamming energy is concentrated on the target area, maximizing the Jamming-to-Signal (J/S) ratio while protecting friendly RF systems located behind the antenna array.

2. Signals Intelligence (SIGINT) & Electronic Support (ES)

For SIGINT operators, the LP-20-3000L is an elite Search and Exploitation tool. Its flat gain response and directional precision are essential for modern digital intercept.

• High-Speed Spectrum Scanning: Provides a consistent 6 dBi gain across the entire 20-3000 MHz range. This allows automated SIGINT receivers to scan the environment without frequency-dependent blind spots, ensuring a high probability of intercept (POI).
• Line-of-Bearing (LOB) Accuracy: The 14 dB front-to-back ratio and clearly defined main lobe allow operators to acquire precise directional data for emitter location and triangulation.
• Low Noise Floor: The D.C. grounded design bleeds off static noise, providing the clean signal path required to detect Low Probability of Intercept (LPI) or "whisper" transmissions that would be lost in the noise of a lower-quality array.

3. Persistent Spectrum Monitoring & Surveillance

The LP-20-3000L is engineered for "Persistent Awareness" in the most punishing environmental theaters.

• Multi-Domain Surveillance: A single LP-20-3000L can monitor:
  • VHF/UHF (20-1000 MHz): Tactical military radios, maritime comms, and aero-band signals.
  • L/S-Band (1000-3000 MHz): SATCOM downlinks, GPS/GNSS, 4G/5G cellular, and drone telemetry.
• Rapid Deployment Agility: The <10 minute assembly time and foldable design make it the primary choice for rapid-response monitoring posts and temporary Tactical Operations Centers (TOCs).
