1-Way (Radio) Path Loss Calculator

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.

The calculator originally on this page has been removed because of compatibility issues with outdated Microsoft OWC components.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 Espresso Engineering Workbook™ for FREE.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB.

The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a lady's voice announced "You've Got Mail" when a new message arrived...
