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.
