LP-200-500

The LP-200-500 is a high-gain, military-grade Log Periodic Dipole Antenna (LPDA) designed for precision directional communication, spectrum monitoring, and electronic warfare across the 200–500 MHz range. Delivering a formidable 11 dBi gain, this antenna provides an elite Jamming-to-Signal (J/S) ratio and extended standoff range for intercepting tactical UHF signals. Engineered with a "pure" LPDA architecture and no efficiency-robbing loading coils, the LP-200-500 ensures linear performance and maximum power density in a ruggedized, field-deployable form factor.

Design: Precision UHF Directionality

The LP-200-500 is optimized for operators who require maximum gain and frequency agility within the primary tactical UHF spectrum.

• Unified 200–500 MHz Coverage: Seamlessly transitions through the critical bands used for military LMR, public safety, and ground-to-air communications. This replaces the need for multiple narrow-band Yagi antennas.
• Exceptional 11 dBi Gain: By focusing RF energy into a narrow 50-degree horizontal beam, the antenna provides significant range extension and signal penetration, essential for neutralizing or intercepting distant emitters.
• High-Power 300W Capacity: Built for continuous-duty transmission, the array handles up to 300 Watts of RF power. This makes it a premier platform for Electronic Attack (EA) and signal saturation.
• Polarization Agility: The mounting bracket is welded at the back end of the dual booms, allowing for rapid field-switching between Vertical and Horizontal polarization to match mission requirements or intercepted signal profiles.

Construction: Ruggedized & Weather-Hardened

Built for 24/7 survivability in the most hostile environmental theaters, from high-salinity coastal zones to extreme tactical mobility.

• Aerospace-Grade Materials: Constructed from 6063T6 architectural anodized aluminum alloy with square-tube booms and round-tube elements. The use of extra spacers between booms ensures mechanical durability against 200 Km/Hr winds.
• Weatherproof Signal Path: The internal coaxial cable is sealed inside the support boom, shielding the signal path from moisture and dust. The entire assembly is finished with an epoxy-based powder coating for maximum resistance to UV radiation and salt spray.
• Modular Tactical Setup: Features removable elements that attach via a fast-deployment stud and nut system, allowing for streamlined logistics and rapid setup by a single operator.
• D.C. Grounded Safety: The antenna operates at D.C. ground, providing a safe discharge path for lightning and bleeding off static noise for high-fidelity spectrum monitoring.

Technical Features

• Consistent 11 dBi Gain: Maintains linear gain and predictable radiation patterns across the entire 300 MHz bandwidth.
• Superior 18 dB Front-to-Back Ratio: Provides excellent isolation, protecting friendly systems behind the antenna while focusing energy on the target sector.
• Optimized VSWR: Precision-engineered to maintain a stable VSWR of 1.8:1 or better, ensuring maximum power transfer and transmitter safety.
• Rear-End Mounting: Mounting clamps are positioned at the rear of the boom to prevent the mounting mast from distorting the radiation pattern.
• Wide Temperature Tolerance: Operates reliably in extreme temperatures ranging from -30°C to +70°C.

EW, SIGINT & Monitoring Compatibility

The LP-200-500 is an elite force multiplier for specialized electromagnetic operations:

• Electronic Warfare (EW): The 300W rating and 11 dBi gain enable surgical, high-intensity jamming of adversary tactical radios and data links.
• Signals Intelligence (SIGINT): The high-gain directional pattern allows for accurate Line-of-Bearing (LOB) acquisition for emitter location and triangulation.
• Spectrum Surveillance: The linear LPDA design provides a flat response for intercepting weak or burst transmissions without frequency-dependent blind spots.
