Assume the repeater antenna is on top of a mountain that is 5000 feet above the surrounding flat terrain and you had a pair of binoculars at the exact height of the antenna.you could see the horizon about 86 miles away ! You can also input tower/antenna height to see how tall either party would need to be in order to accomplish line of sight.

The signal path line overlay (shown on the chart in red) represents the direct line-of-sight To guarantee reception of VHF and UHF radio signals we ideally want a clear line of sight between our location and the location of the signal we want to receive RF Line-of-Sight provides radio paths for mapping long distance SCADA radio communications by using antenna height and topography
FGC Presents Line of Sight Mapping in FG Unity with community mapper Moepsii! YouTube. RF Line-of-Sight The RF Line-of-Sight tool allows users to easily drag-and-drop locations and obtain point-to-point line-of-sight information anywhere using Google Maps Assume the repeater antenna is on top of a mountain that is 5000 feet above the surrounding flat terrain and you had a pair of binoculars at the exact height of the antenna.you could see the horizon about 86 miles away !
Calibrating beyond line of sight RF modelling with field testing CloudRF. Longley Rice simulations of radio coverage, either as "bullseye" (signal level) or "Line of Sight" images; Path Profile Analysis between two stations; Downloadable files in KMZ format for use with Google Earth or other applications; SignalServer can do a lot more - if your needs are more elaborate we recommend installing SignalServer yourself. Click two locations on the map to create an elevation profile between the 2 points, the start point is indicated by a green pin and the end point by a red pin.
