A suite of three site planning apps that turn real elevation data into clear, confident answers — before you climb the tower, mount the dish, or install the panel.
SiteLine Planner is a focused toolkit for anyone who needs to understand a piece of land before installing equipment on it. Built on USGS terrain data — no guessing, no rough estimates.
USGS 1/3 arc-second elevation — about 10-meter resolution across the United States. Honest profiles, not flat-earth math.
See exactly what's between you and your target — towers, satellites, the sun. Identify obstructions before they cost you time on a roof or a tower.
Enter coordinates or use device location on demand. We don't run analytics, sell data, or show ads. Your plans stay yours.
Each app is purpose-built for a specific kind of installer. Same terrain engine, different lens.
Ham radio antenna planning
Plan antenna placement with real terrain analysis. See your radio horizon, find blocking ridges, and pick a tower height that actually clears them.
Satellite dish pointing
Get exact azimuth and elevation to any satellite — DirecTV, Dish Network, HughesNet, or Starlink. Catch obstructions before you drill a hole in the roof.
Solar panel placement
Sun-path analysis and shading models for any roof or yard. Get optimal tilt and azimuth, plus realistic yield estimates that account for terrain shadows.
