How do I use HDPath to plot a basic path profile?

HDPath is used for setting up the end point sites and facilities for a path study and for changing parameters (such as effective earth curvature or surface features) that affect the analysis of that path.

Drawing a Basic Profile

HDPath presents almost all of the pertinent path information on a single form. When HDPath is launched, the path form is displayed:

Path Form

This form displays two instances of the Fixed Facility Database Interface, shown on the left and right sides of the form. These sections are used to set up the end points for the path.

By convention, the left side of the form is considered the Transmit site, so the relevant parameters (transmit antenna height, etc) are used for that record. The right side of the form is considered the Receive site, so the receiver antenna height is used for that site.

The easiest way to draw a profile is to find the desired records in the Fixed Facility Database. Find the site you want for each end of the path using the dropdown list at the bottom of the form:

When desired sites are displayed, click the Draw button, which has the pencil icon in the upper toolbar. The path will be displayed.
