Tips & Tricks

• A modern web browser is recommended due to the heavy use of JavaScript and the large result sets that can be returned.
• Works great on mobile browsers. Check "Use current location" to use your phone's GPS to determine your location.
• Zoom right down to "street view" level to view towers & transmitters from street level.
• The "Tabular" results page (link at top right of map) can be copied and pasted into many programs, such as Microsoft Excel and Freescan's EZGrab function.
