Professional Terrain-Aware RF Coverage for Amateur Radio Operators

Understanding how far your signal truly reaches is essential for modern amateur radio operations. 9M2PJU PRO SIGNAL transforms signal analysis with a high-performance, terrain-aware coverage engine designed for operators who demand accuracy, insight, and actionable field data.

Unlike conventional tools that rely on simple circular coverage estimates, PRO SIGNAL uses real-time terrain data and advanced propagation modeling to show where your RF signals genuinely reach—and where they are blocked.

🏔️ Precision Terrain Shadowing

PRO SIGNAL employs a 72-radial sampling grid combined with the Open-Elevation API to analyze topography and obstacles along each path. Using knife-edge diffraction and the Okumura-Hata suburban model, it accounts for:

• Hills, ridges, and buildings
• Signal shadowing and diffraction effects
• Dead zones and low-signal areas

The result is a realistic, map-based visualization that lets operators see exactly where their signals perform best.

📱 Native Mobile Experience

The dashboard is fully optimized for mobile use, allowing operators to perform field analysis on the go:

• Swipe-up bottom sheet: Quick access to settings without obstructing the map
• Floating Scan Button (FAB): One-tap signal coverage scanning
• Haptic-ready metrics: Large, touch-friendly cards display area statistics

With mobile-first design, PRO SIGNAL brings desktop-grade analysis to handheld devices.

📶 Multi-Band RF Performance

Whether you operate VHF, UHF, or SHF, PRO SIGNAL delivers:

• Frequency range support: 30 MHz – 3 GHz
• Automatic Height Above Average Terrain (HAAT) estimation
• Real-time service-grade mapping across multiple tiers:

This provides a clear and actionable understanding of your coverage in every operational context.

🔬 Advanced Signal Modeling

PRO SIGNAL combines mathematical rigor with intuitive visualization:

• Okumura-Hata propagation model for median path loss
• HAAT calculation sampling 8 points per radial to estimate true antenna height
• Knife-edge diffraction to model shadowing over terrain obstacles

The outcome is scientifically grounded coverage data, delivered in a visually digestible, interactive format.

🗺️ Real-Time Coverage Visualization

• Interactive Leaflet map shows terrain-aware signal propagation
• Multi-layer support highlights signal grades, dead zones, and coverage gaps
• Dynamic scanning lets you assess new locations in seconds

With PRO SIGNAL, every operator can make data-driven decisions about antenna placement, power, and operational strategy.

🛠️ Cutting-Edge Technology Stack

• Core: React 18, Vite JS
• GIS & Mapping: Leaflet, Open-Elevation API
• Design: Glassmorphism + mobile-native UI components
• Logic: Custom Hata-Okumura terrain-blocking engine
• Icons: Lucide-React

This ensures high performance, modern aesthetics, and responsive, reliable operation across all devices.
