Greetings: There is so much good stuff on RF Cafe that there is no way to list or
link to all of it here. Please use the Search box or the Site
Map to find what you want - there is a good chance I have it. Thanks!
This 1-way path loss calculator uses the familiar Friis equation. It is
applicable in the case of something like a transmitter broadcasting to a distant receiver. The transmission medium
is assumed to be air in a line-of-site configuration.
As a rule of thumb, do not specify a distance (d)
less than the wavelength or the results become unreliable.
The calculator originally on this page has been
removed because of compatibility issues with outdated Microsoft OWC components. A 1-Way Path Loss
Calculator is included in
RF Cafe Calculator Workbook for FREE.
