Users can simply click on two points on the topographic
map to create a terrain profile and to check path
obstructions and proper Fresnel zone clearance.
RFCAD will display the terrain between the two points
as well as the line of sight from the transmitter
to the receiver. In addition, users may plot the
minimum Fresnel Zone clearance and a complete tabular
display of the terrain. Users may also alter the
height of either the transmitter or receiver to
depict various height possibilities, as well as
to change the profile length itself. Users may also
chose to display the Loss for the profile, as well
as color the terrain by signal strength.
