LP-50-500

The LP-50-500 is a military-grade, high-gain Log Periodic Dipole Antenna (LPDA) engineered for broadband directional transmission and reception across the 50–500 MHz spectrum. Covering nearly the entire VHF and lower UHF bands, this unified aperture is a critical asset for tactical communication, signal intelligence (SIGINT), and high-power jamming missions. By utilizing a full-sized, "pure" LPDA architecture without efficiency-robbing loading coils, the LP-50-500 delivers a consistent 9 dBi gain and linear performance, ensuring maximum electronic dominance and situational awareness in the field.

Design: Wideband Directional Dominance

The LP-50-500 is optimized for mission-critical hubs requiring high power density and frequency agility across a massive 450 MHz bandwidth.

• Unified VHF/UHF Coverage: Seamlessly covers the transition from Low-VHF tactical combat nets (50 MHz) through to the high-UHF bands (500 MHz) used for public safety and military data links.
• High-Intensity 500W Power Handling: Engineered for continuous-duty Electronic Attack (EA) and jamming, this array manages up to 500 Watts of RF power, ensuring a dominant Jamming-to-Signal (J/S) ratio.
• Superior 9 dBi Directional Gain: By compressing RF energy into a 75-degree horizontal beam, the antenna effectively triples the range of standard dipole antennas, providing significant standoff capability for monitoring and denial.
• Linear Pure-Element Performance: Unlike compact antennas that use loading techniques, the LP-50-500 uses full-sized architecture. This ensures no "notches" in gain and maximum electrical efficiency across the entire band.

Construction: MIL-SPEC Hardening & Rapid Deployment

Built for the rigors of modern theater, the LP-50-500 balances its massive 3-meter width with extreme tactical agility.

• 5-Minute Rapid Assembly: Designed for high-mobility units, the antenna can be fully assembled by two technicians in under 5 minutes. It features foldable elements and a fast-deployment stainless steel stud system at marked positions on the support boom.
• Aerospace & Marine-Grade Materials: Constructed from 6063T6 anodized aluminum alloy and Type 316 marine-grade stainless steel fasteners. The array is finished with an epoxy-based Military Olive Green powder coating to resist salt fog, acid rain, and UV degradation.
• D.C. Grounded for Signal Purity: The antenna operates at D.C. ground, providing a safe discharge path for lightning and bleeding off static noise. This ensures an ultra-clean noise floor for intercepting weak signals during SIGINT missions.
• Polarization Flexibility: The central mounting arrangement allows for easy field-rotation between Horizontal and Vertical polarization to match mission requirements or intercepted signal profiles.

Technical Features

• Unified 50–500 MHz Coverage: Single-point feed point for the entire 450 MHz tactical band.
• Directional Precision: 75-degree horizontal beamwidth optimized for scanning and jamming.
• MIL-STD-810G Certified: Rigorously tested for shock, vibration, salt fog, rain, and extreme temperatures.
• High Durability: Extra spacers between square-tube support booms improve structural rigidity against 195 Km/Hr winds.
• Low VSWR Performance: Precision-tuned to maintain a VSWR better than 2.5:1 across the entire bandwidth.
• Input Termination: High-power rated N-Female connector for secure coaxial integration.

EW, SIGINT & Monitoring Compatibility

The LP-50-500 is an elite force multiplier for specialized electromagnetic operations:

• Electronic Warfare (EW): The 500W rating and 9 dBi gain enable surgical, high-intensity jamming of adversary tactical radios and RCIED triggers across the VHF/UHF spectrum.
• Signals Intelligence (SIGINT): The high-gain directional pattern allows for accurate Line-of-Bearing (LOB) acquisition, enabling teams to triangulate and locate enemy transmitters.
• Persistent Monitoring: Its rugged build and D.C. grounding provide a high signal-to-noise ratio, perfect for long-term spectrum surveillance in harsh environmental theaters.
