LP-700-2500

Overview: LP-700-2500 High-Performance Log Periodic Dipole Antenna

The LP-700-2500 is an elite, military-grade Directional Log Periodic Dipole Antenna (LPDA) precision-engineered for the 700 – 2500 MHz (extending to 2700 MHz) wideband spectrum. Housed in a high-tech fiberglass radome, this antenna is designed for mission-critical applications including electronic warfare, SIGINT, tactical communications, and high-power jamming. By utilizing a fully welded 6063T6 aluminum array and avoiding efficiency-reducing loading techniques, the LP-700-2500 delivers a consistent 9 dBi gain across its entire operating window, ensuring absolute signal dominance in the most punishing theater environments.

Hardened Construction & Radome Shielding

Strategic engineering for zero-failure performance in severe environments. The LP-700-2500 is built using 6063T6 ultra-corrosion-resistant architectural anodized aluminum alloy. Every radiating element is fully welded to the square-tube support booms, a critical feature that prevents mechanical loosening and eliminates RF inter-modulation (IM). The internal array is completely protected within a ruggedized fiberglass radome, which is transparent to RF signals but provides a resilient shield against ice formation, corrosive gases, and desert sandstorms. All fasteners are made of marine-grade stainless steel, and the entire unit is finished with a durable olive green powder coating for enhanced resistance to salt fog and UV radiation.

Operational Efficiency & Pattern Precision

Directional mastery with high-power signal concentration. The antenna delivers a focused 60-degree horizontal beamwidth and a robust 18 dB Front-to-Back ratio, allowing for precise signal targeting while minimizing interference from the rear. Unlike compact antennas that use loading coils, the LP-700-2500 maintains high efficiency and strong gain throughout the entire band. For safety and signal purity, the antenna operates at direct DC ground, providing a low-resistance discharge path for lightning protection and high immunity to atmospheric static.

Detailed Technical Features

• Ultra-Wideband Versatility: Seamlessly covers the 700 to 2700 MHz range, ideal for GSM, LTE, Wi-Fi, and tactical UHF/L/S-band applications.
• Radome-Shielded Array: The tapered fiberglass enclosure reduces wind loading and prevents the "detuning" effects of environmental ingress.
• High-Power Capacity: Engineered to handle up to 150 Watts of continuous RF power, facilitating robust tactical broadcasting and area denial.
• Inter-Modulation (IM) Suppression: Fully welded elements prevent the "diode effect" common in non-welded designs, ensuring a clean noise floor.
• Versatile Polarization: The mounting arrangement allows for immediate installation in either Vertical or Horizontal polarization.
• Low-Loss Termination: Output is provided via a high-quality coaxial cable with a fixed N-Female termination at the back end for secure connectivity.
• Integrated Lightning Protection: Direct grounding ensures the safety of sensitive connected receivers and transmitters.
• Compact Tactical Footprint: At only 450 mm (18 inches) long, the antenna offers an exceptional gain-to-size ratio for rapid field deployment.

Detailed Environmental Features (MIL-STD-810G Hardened)

The LP-700-2500 is built and tested to meet the most stringent defense standards:

• High-Velocity Wind Stability: Aerodynamically optimized to survive constant winds up to 200 Km/Hr.
