LP-20-3000

The LP-20-3000 is a strategic-grade, ultra-wideband Log Periodic Dipole Antenna (LPDA) engineered for total spectrum dominance from 20 MHz to 3000 MHz. This massive 6.2-meter array provides a unified, "single-unit" solution for the entire modern tactical landscape—spanning legacy low-VHF ground nets, SINCGARS, military aviation, public safety, 4G/5G LTE, and S-Band satellite links. Built from 6063T6 architectural aluminum and featuring a rapid-assembly foldable design, it is the definitive choice for high-power jamming, SIGINT, and wideband monitoring in mission-critical theater environments.

Design: Global Spectrum Visibility & Tactical Response

The LP-20-3000 is engineered for operators who require "total spectrum visibility" starting from the very low end of the VHF band (20 MHz) all the way to microwave frequencies (3 GHz).

• Massive Frequency Coverage: Replaces multiple dedicated antennas by covering everything from 20 MHz tactical ground nets to 3 GHz microwave data links.
• Rapid Tactical Response: Despite its expansive 7.5-meter width, the antenna features foldable, segmented elements and a segmented support boom. Two technicians can fully assemble the array in less than 10 minutes, making it ideal for "jump" missions and mobile command posts.
• Unloaded Element Integrity: By utilizing full-sized radiating elements rather than lossy loading techniques, the LP-20-3000 maintains a stable 6–9 dBi gain and superior radiation efficiency across nearly seven octaves of bandwidth.

Construction: Industrial & Marine Hardening

Constructed from 6063T6 architectural anodized aluminum alloy, the LP-20-3000 is built for strategic longevity in the world's most severe climates.

• Marine-Grade Durability: All fasteners (screws, nuts, and bolts) are made of Type 316 marine-grade stainless steel. The entire unit is finished with a protective powder coating for total corrosion resistance in saline coastal or monsoon environments.
• Integrated Safety: Operates at D.C. ground, providing a low-resistance discharge path for lightning protection and suppressing atmospheric static for an ultra-quiet noise floor during sensitive SIGINT operations.
• Mechanical Resilience: Extra spacers between support booms and a stainless steel stud system with spring washers ensure the antenna remains stable under high vibration and wind loads up to 160 Km/Hr.

Reliability: 1000W Multi-Mission Power

With a continuous 1000 Watt power handling capacity at 1 GHz (500W at 3 GHz), the LP-20-3000 is robust enough for high-intensity jamming. The wide 100-degree horizontal beamwidth acts as a powerful directional "floodlight," while the 15 dB Front-to-Back ratio ensures energy is focused on the target while shielding personnel behind the boom.

Technical Features

• Comprehensive 20–3000 MHz Coverage: One antenna for Low-VHF, High-VHF, UHF, and S-Band.
• Fast 10-Minute Assembly: Foldable/segmented elements and boom for streamlined logistics.
• 1000W High Power Handling: Optimized for electronic countermeasures (ECM).
• Dual Polarization Brackets: Permanently fitted brackets allow for rapid switching between Vertical and Horizontal orientation.
• Shipping Length of 3.0 Meters: Fits into standard tactical transport containers.
• Center-Boom Mounting: Securely fits 50mm to 77mm (2-3 inch) heavy-duty masts.
• Direct Ground Protection: Integrated lightning protection and enhanced noise immunity.

Integration Guide: Dominating the Tactical Spectrum

1. Defeating Signal Fading & Obstacles

Across this massive range, signals behave differently. Lower frequencies (20-88 MHz) diffract over hills, while higher frequencies (1000-3000 MHz) reflect like light. The LP-20-3000's dual-polarization brackets allow you to match the orientation of the incoming wave—whether horizontal or vertical—to maintain a stable link in any terrain.

2. Tactical Jamming & J/S Ratio

Projecting 1000 Watts across the wide 100-degree beamwidth allows for broad-sector suppression of enemy networks. The directional gain concentrates power forward, exponentially increasing your Effective Radiated Power (ERP) compared to an omnidirectional antenna.

3. SIGINT Sensitivity

For sensitive monitoring, the D.C. Grounded design is vital. It bleeds off the "static crackle" built up by wind moving across the large 7.5-meter width, ensuring you can detect weak, low-power transmissions that would be buried in the static of an ungrounded system.

Strategic EW & SIGINT Guide: 20–3000 MHz Global Spectrum Dominance

The LP-20-3000 is a theater-level strategic asset. Spanning nearly seven octaves of bandwidth, it is one of the few antennas in the world capable of covering the entire tactical landscape—from Very Low Frequency (VLF) ground waves to S-Band microwave data links—with a single, high-power aperture. In an era of multi-domain operations, this antenna provides the raw power and directional precision needed to intercept and disrupt any signal in the modern battlespace.

1. Exploiting Propagation Diversity

Across the 20–3000 MHz range, radio waves transition through three distinct propagation modes. The LP-20-3000 is engineered to master all of them:

• Diffraction (20–100 MHz): Long wavelengths bend over hills and around obstacles. This allows you to monitor or jam "over-the-horizon" tactical nets.
• Tropospheric & Line-of-Sight (100–1000 MHz): Ideal for ground-to-air (ATC) and tactical SATCOM intercepts.
• Reflective/Optical (1000–3000 MHz): Signals reflect sharply off urban structures. The antenna’s 9 dBi gain allows you to isolate these reflections to "see" around corners in dense cities.

2. Tactical Stealth & Boresight Ambiguity

In Electronic Warfare, the physical profile of an antenna can reveal a team's intent.

• Visual Deception: Because the LP-20-3000 contains elements for the entire 20–3000 MHz range, an adversary cannot tell simply by looking at the 7.5-meter array which specific band is being targeted.
• Broad-Sector Coverage: The 100-degree beamwidth allows for "blanket" monitoring of an entire tactical sector, capturing multiple frequency-hopping nets simultaneously without needing to constantly re-align the mast.

3. High-Power Jamming & J/S Ratio Optimization

To successfully disrupt an adversary’s communication, you must achieve a superior Jamming-to-Signal (J/S) ratio at their receiver.

• 1000W Low-Band Power: At the lower end of the band, the LP-20-3000 handles a massive 1 Kilowatt. This allows for the total suppression of enemy tactical VHF nets over a vast geographic area.
• Microwave Precision: At 3 GHz, the antenna focuses 500W of power into a directional cone. This concentration exponentially increases your Effective Radiated Power (ERP), allowing you to "drown out" high-speed data links or drone command signals from several kilometers away.

4. "Silent" Monitoring: D.C. Grounding & Noise Floor

For sensitive SIGINT operations, the "Noise Floor" is the ultimate enemy. Wind moving across a large 7.5-meter array creates "Precipitation Static" (P-Static), which sounds like an electronic hiss in the receiver.

• The Solution: The LP-20-3000 is D.C. Grounded. It constantly bleeds off this static charge to the mast and earth. This ensures the lowest possible noise floor, allowing you to detect weak, "hidden" transmissions or frequency-hopping signals that would be buried in the static of an ungrounded system.

Tactical Deployment Checklist

• Dual-Polarization Jump: Utilize the pre-fitted brackets. In a tactical "jump," you may only have seconds to change polarization. Having both brackets permanently attached to the boom allows you to flip the antenna 90 degrees instantly to match a target's signal orientation.
• Rapid 10-Minute Setup: Take full advantage of the foldable, segmented elements. In modern EW, if you stay in one place too long, you become a target. The LP-20-3000's speed of assembly/disassembly is a survivability feature.
• High-Power Cable Management: When running at 1000W, use LMR-600 or corrugated copper feeders. Standard cables will suffer dielectric breakdown or overheat, leading to catastrophic VSWR failure.
• Mast Integrity: At 40 Kgs and 7.5 meters wide, this antenna exerts massive wind load. Ensure your mast is at least 3 inches in diameter and properly guyed. A swaying mast will cause signal "scintillation," making it harder to maintain a lock on high-frequency microwave targets.
