LP-30-1300

The LP-30-1300 is a strategic-grade, ultra-wideband High Gain Log Periodic Dipole Antenna (LPDA) engineered for comprehensive directional coverage across the 30–1300 MHz spectrum. This expansive 4.8-meter array serves as a unified solution for the entire tactical communication landscape, spanning legacy VHF (SINCGARS), military aviation (UHF), public safety networks, and L-band monitoring. Constructed from 6063T6 architectural aluminum and featuring a fast-deployment self-locking mechanism, it is the definitive choice for high-power jamming, SIGINT, and wideband scanning in mission-critical environments.

Design: Total Spectrum Visibility & Rapid Response

The LP-30-1300 is designed for operators who require "total spectrum visibility" without the logistical burden of swapping antennas for different frequency bands.

• Ultra-Wideband Efficiency: Replaces multiple dedicated antennas by covering everything from 30 MHz tactical ground nets to 1.3 GHz L-band telemetry.
• Self-Locking Fast Deployment: Despite its 5-meter width, the antenna features foldable, segmented elements and a fast-deployment self-locking device. This allows a team of two to fully assemble the array in less than 10 minutes, making it ideal for "jump" missions and mobile command posts.
• Non-Loaded Performance: Unlike compact antennas that use lossy loading techniques, the LP-30-1300 utilizes full-sized elements to ensure a stable 8 dBi gain and superior radiation efficiency across the entire band.

Construction: Industrial & Marine Hardening

Constructed from 6063T6 architectural anodized aluminum alloy, the LP-30-1300 is built for strategic longevity in the world's most severe climates.

• MIL-STD-810G Certified: Rigorously tested for extreme temperature, shock, rain, and salt fog. It is specifically treated for survival in coastal or monsoon environments where standard equipment fails.
• Marine-Grade Hardware: All fasteners are made of Type 316 marine-grade stainless steel. The unit is finished with an electrostatic Epoxy Powder Coating for total corrosion resistance.
• Integrated Safety: Operates at D.C. ground, providing a low-resistance path for lightning protection and suppressing atmospheric static for an ultra-quiet noise floor during sensitive SIGINT operations.

Reliability: 500W Multi-Mission Power

With a continuous 500 Watt power handling capacity, the LP-30-1300 is robust enough for high-intensity jamming. The wide 100-degree horizontal beamwidth acts as a powerful directional "floodlight," while the 16 dB Front-to-Back ratio ensures energy is focused on the target while shielding personnel behind the boom.

Technical Features

• Comprehensive 30–1300 MHz Coverage: One antenna for VHF, UHF, and L-Band monitoring.
• Self-Locking Rapid Deployment: Elements attach instantly for fast tactical setups.
• 500W High Power Handling: Optimized for electronic countermeasures (ECM).
• MIL-STD-810G Compliance: Engineered for extreme shock, vibration, and salt-fog.

• Center-Boom Mounting: Securely fits 38mm to 75mm (1.5-3 inch) heavy-duty masts.
• Direct Ground Protection: Integrated lightning protection and enhanced noise immunity.

Integration Guide: Dominating the Tactical Spectrum

1. Defeating Multi-Path & Signal Fading

In complex urban or mountainous terrain, signals reflect and rotate. The LP-30-1300's flexible mounting permits both Vertical and Horizontal orientation, allowing you to match the polarization of the incoming wave—essential for maintaining a stable link when standard whips experience massive signal "nulls."

2. Tactical Jamming & J/S Ratio

Projecting 500W across the wide 100-degree beamwidth allows for broad-sector suppression of enemy tactical networks. The directional gain concentrates power forward, exponentially increasing your Effective Radiated Power (ERP) compared to an omnidirectional whip.

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 5-meter array, ensuring you can detect weak, low-power transmissions that would be buried in the static of an ungrounded system.

EW & Monitoring Guide: 30–1300 MHz Tactical VHF/UHF Mastery

The LP-30-1300 is a powerhouse "all-in-one" tactical asset. Spanning from 30 MHz to 1.3 GHz, it bridges the critical gap between legacy low-band ground communications (SINCGARS) and modern high-band aeronautical and telemetry links. In a battlespace defined by frequency-hopping and complex terrain, the LP-30-1300’s 8 dBi gain and physical adaptability provide a definitive edge.

1. Exploiting Ground-Wave & Diffraction (30–88 MHz)

At the lower end of the spectrum, signal wavelengths are long (up to 10 meters). These waves have the unique ability to "diffract"—literally bending over the horizon or around large obstacles like mountains and dense forests.

• The Polarization Advantage: While most tactical vehicle whips are vertically polarized, terrain and foliage can cause significant signal rotation.
• Tactical Diversity: The LP-30-1300 allows operators to quickly switch to Horizontal polarization. In heavily wooded or mountainous terrain, this can often "find" a cleaner, stronger signal path that a standard vertical whip would miss entirely.

2. Mastering the 225–400 MHz Aviation Band

The UHF portion of the LP-30-1300's range is the primary home for military air-to-ground and air-to-air communications.

• High-Gain Intercept: With 8 dBi of gain, this antenna can pull in weak aeronautical transmissions from aircraft at extreme distances. Every 6 dB of gain effectively doubles your reception range, allowing SIGINT teams to monitor air corridors long before targets enter the immediate operational area.
• Directional Triangulation: The 100-degree horizontal beamwidth acts as a powerful directional sensor. By rotating the antenna, teams can identify the exact bearing of incoming or outgoing aircraft, providing vital early warning data.

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

To successfully disrupt an adversary’s frequency-hopping tactical net or a UHF data link, you must achieve a superior Jamming-to-Signal (J/S) ratio at the victim’s receiver.

• 500W Strategic Power: The LP-30-1300 acts as a directional "floodlight." Its 8 dBi gain acts as an RF magnifying glass, concentrating massive energy into a focused cone.
• Denial of Service: By concentrating power, you saturate the victim's receiver front-end. This makes it impossible for their radio to maintain "sync" with a hopping sequence, effectively blacking out their command and control.

4. "Silent" Monitoring: D.C. Grounding & Static

For sensitive SIGINT operations, the "Noise Floor" is the ultimate enemy. High-speed wind or dry air moving across the large elements of a 5-meter array creates "Precipitation Static" (P-Static).

• The Solution: The LP-30-1300 is D.C. Grounded. It constantly bleeds off static charge to the mast and earth. This ensures the lowest possible noise floor, allowing you to detect low-power "hidden" transmissions or weak signals that would be buried in the static of an ungrounded antenna.

Tactical Deployment Checklist

• Rapid 10-Minute Setup: Take full advantage of the self-locking elements. In a tactical "jump" or mobile intercept mission, speed is survival. Ensure the segments are securely seated to maintain VSWR stability.
• Mast Stability: At 30 Kgs and 5 meters wide, this antenna exerts significant wind load. Ensure your mast (up to 3 inches) is properly guyed. A swaying mast causes signal "scintillation," making it harder to maintain a lock on a distant target.
• Cable Integrity: When running at 500W, use LMR-400 or LMR-600. Standard cables can overheat during continuous-duty high-power jamming.
• Boresight Alignment: Because the beamwidth is 100 degrees, a 50-degree alignment error will drop your gain significantly. Use a compass to ensure the antenna is pointed exactly at the target sector for maximum intercept probability.
