LP-200-2500

The LP-200-2500 is a versatile, high-gain Tactical Log Periodic Dipole Antenna designed for high-performance directional communication across the 200–2500 MHz spectrum. Delivering a stable 9 dBi gain in a highly portable 1.2-meter frame, this antenna is the definitive multi-band solution for UHF aviation, GSM/LTE cellular, and S-Band tactical data links. Its non-loaded, 6063T6 aluminum architecture ensures maximum radiation efficiency and mechanical integrity, making it a primary asset for both rapid-deployment mobile missions and permanent installations in severe environments.

Design: Multi-Band Dominance & Tactical Response

The LP-200-2500 is engineered for operators who require "total spectrum visibility" across the critical UHF and microwave bands (0.2 GHz to 2.5 GHz).

• Precision 9 dBi Gain: By utilizing a full-sized, non-loaded array design, the antenna achieves exceptional gain and a focused 55-degree horizontal beamwidth. This allows for extreme precision in signal targeting and significantly increased range compared to standard broadband antennas.
• High-Power Strategic Variant: While the standard unit handles 180 Watts at the high end, an optional 650W version is available for high-intensity Electronic Countermeasures (ECM) and strategic jamming operations.
• Rapid Tactical Logistics: With an overall length of 1.2 meters and a weight of only 3.5 Kgs, this antenna is highly portable. It features removable elements and can be fully assembled by a single technician in less than 5 minutes, making it ideal for "jump" missions.

Construction: Combat-Tier Hardening

Constructed from 6063T6 architectural anodized aluminum alloy, the LP-200-2500 is built for a long service life in active combat zones.

• MIL-STD-810G Certified: Rigorously tested for extreme temperature (-40 to +70°C), shock, vibration, rain, and salt fog. It is specifically engineered to thrive in coastal, monsoon, or desert environments.
• Marine-Grade Hardening: All fasteners are made of high-quality marine-grade stainless steel. The entire array is protected by an electrostatic Epoxy Powder Coating of military green color for total corrosion resistance.
• Integrated Safety: Operates at D.C. ground, providing a low-resistance discharge path for lightning and suppressing atmospheric static to ensure an ultra-quiet noise floor for high-sensitivity surveillance.

Technical Features

Integration Guide: Dominating the Multi-Band Spectrum

1. Isolating Modern Tactical Signals

Across the 200-2500 MHz range, the RF environment is often "congested." A standard wideband antenna "sees" everything, which can overwhelm a receiver.

• The Precision Advantage: The focused 55-degree beamwidth of the LP-200-2500 acts as a directional "spotlight." This allows an operator to isolate a specific cell tower or tactical data link while physically "nulling out" interference from the sides and rear.

2. Tactical Jamming & J/S Ratio Optimization

When projecting high power, the 9 dBi gain acts as an RF magnifying glass, concentrating energy into a focused cone. This concentration exponentially increases your Effective Radiated Power (ERP), allowing you to "drown out" adversary communications at extended ranges.

3. Polarization Agility

Most tactical and cellular systems are vertically polarized, but reflections off urban structures rotate signals. The LP-200-2500’s flexible mounting permits both Vertical and Horizontal orientation, ensuring you can match the orientation of the incoming wave to maintain a stable intercept.

Strategic EW & SIGINT Guide: 200–2500 MHz Multi-Band Dominance

The LP-200-2500 is a surgical strike tool for the 0.2 to 2.5 GHz spectrum. This range is the operational backbone for modern digital life and military coordination, hosting UHF military aviation, TETRA, GSM/LTE cellular, and S-Band data services. At these frequencies, radio waves behave with "optical" precision, making the LP-200-2500’s 9 dBi gain and directional accuracy mandatory for mission success.

1. High-Gain Directional "Spotlight"

In the 200–2500 MHz band, the RF environment is often "congested." A standard wideband antenna sees everything, which can overwhelm a receiver with background noise.

• The Precision Advantage: The 9 dBi gain and focused 55-degree horizontal beamwidth of the LP-200-2500 act as an RF "spotlight." This allows an operator to isolate a specific cell tower or a single tactical repeater while physically "nulling out" interference coming from the sides or rear.
• Range Extension: Every 6 dB of gain effectively doubles your reception range. The 9 dBi gain allows you to pull in weak tactical signals from distances where standard dipole antennas would only see static.

2. Defeating Urban Multipath & Polarization Rotation

Signals at these frequencies reflect sharply off glass, metal, and concrete. Each reflection can cause the signal's polarization to shift or rotate entirely.

• The "Null" Problem: Most tactical handhelds and vehicle whips are vertically polarized. If a signal reflects off a slanted roof, it may arrive at your site with a significant horizontal shift. A standard vertical antenna would experience a signal dropout of up to 20 dB.
• The Tactical Solution: The LP-200-2500 features a flexible mounting arrangement that allows operators to switch between Horizontal and Vertical polarization in seconds. This ensures you can match the orientation of the incoming reflected wave to maintain a stable, high-fidelity intercept.

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

To successfully disrupt a target link (e.g., a high-speed LTE data link or a 400 MHz trunked system), you must achieve a superior Jamming-to-Signal (J/S) ratio at the victim’s receiver.

• Power Density Focus: Instead of scattering 650W in all directions, the LP-200-2500 focuses that energy into a concentrated 55-degree cone.
• ERP Advantage: This concentration exponentially increases your Effective Radiated Power (ERP). You can successfully "drown out" a legitimate signal from several kilometers away, even when the adversary is using high-power mobile transmitters.

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

For sensitive SIGINT operations, the "Noise Floor" is the ultimate enemy. High-speed wind or dry air moving across antenna elements creates Precipitation Static (P-Static), which sounds like an electronic hiss in the receiver.

• The Solution: The LP-200-2500 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 low-power "hidden" transmissions or frequency-hopping signals that would be buried in the static of an ungrounded system.

Tactical Deployment Checklist

• Cable Integrity: At 2500 MHz (2.5 GHz), cable loss is severe. Avoid standard RG-58. Use LMR-400 or LMR-600. Every 3 dB of cable loss effectively cuts your jamming power or reception sensitivity in half.
• Rapid 5-Minute Setup: Take full advantage of the removable elements. In modern EW, speed is survival. The LP-200-2500's speed of assembly (under 5 minutes) is a key survivability feature for "jump" missions.
• Mast Stability: At 3.5 Kgs and 1.2 meters long, this antenna has a low wind profile but still requires a stable mast (up to 2 inches). A swaying mast will cause the 55-degree beam to "shimmer," making it harder to maintain a lock on a distant target.
• Boresight Alignment: Because the beamwidth is 55 degrees, a 25-degree error in alignment will drop your gain significantly. Use a compass to ensure the antenna is pointed exactly at the target sector for maximum intercept probability.
