GBPPR Microwave Radio Path Analysis Tools

A Perl CGI program to graphically show the radio path profile between two points.  It will plot the 0.6 Fresnel zone and the true radio path for a given value of K (the effective Earth radius factor).  This is all displayed in reference to the path's elevation data taken at intervals along the link path.  This will let you see if you have a clear radio line-of-sight path.  Currently, the elevation data is only available for most of North America.  It is also extremely CPU intensive, so please be patient for the output PDF file to complete, or try again at a different time.

All the plotting utilities are based around a slightly modified version of the SPLAT! program by KD2BD.
