PAC LOS - Predicted Area Coverage - Line of Sight   

Coverage contours or view shed analysis of terrain from a tower site.

PAC LOS Coverage Plot

A few things are required to generate the LOS coverage contours: elevation data (free on internet), tower latitude / longitude coordinates, tower height AGL, receiver height AGL, radius of coverage area, earth curvature and Fresnel zone values. Pretty straight forward.

Either single or multiple coverage contours can be imported into PAC LOS. Overlay features such as TX and RX site markers, antenna sector footprints, and range rings can be placed or "overlayed" onto the coverage contours.

Overlay features can be turned on/off. Mouse click to adjust settings, colors, or turn-on/off of overlay features. User created Excel spreadsheet is used for data import of some overlay feature information.
