RF Fresnel Calculator

Plan point-to-point links in seconds: Fresnel radius, earth bulge, antenna heights and free-space path loss from any site. Works in metric or imperial.

Design, analyze, and optimize your wireless links with professional-grade precision. RF Fresnel - Link Planner Pro is the ultimate tool for engineers, network installers, and telecommunications experts to ensure reliable point-to-point and area-wide communication.

Stop guessing and start calculating. Whether you’re deploying a WISP network, a microwave backhaul, or a simple ham radio link, RF Fresnel provides comprehensive terrain profiles, Fresnel zone analysis, and advanced coverage tools to guarantee a clear Line of Sight (LOS). Key Features

• Multi-Source Terrain Data: Seamlessly integrates with Google Elevation, Open-Meteo, and OpenTopoData to provide high-resolution elevation profiles anywhere in the world.
• Visual Fresnel Analysis: View real-time interactive charts showing Terrain, Line of Sight (LOS), the 1st Fresnel Zone, and the critical 60% clearance zone.
• Smart Height Recommendations: If your link is obstructed, the app automatically calculates the exact antenna height increase needed at either end to clear the path.
• Detailed Link Reports: Get precise Azimuth, Elevation angles, Spherical distance, and Ground elevation data for both sites.
• Professional Exporting: Save your analysis, take high-quality screenshots, export interactive KMZ files, and share detailed reports with clients or teammates instantly.
