How do I calculate path loss for RF signals?

Free space path loss depends on frequency and distance. This calculator uses standard formulas to estimate RF signal attenuation.

What is dBm and how do I convert it?

dBm is decibels relative to 1 milliwatt. 0 dBm = 1 mW, +30 dBm = 1 W, -30 dBm = 1 μW. This converter handles RF power unit conversions.

RF calculations are essential for antenna design, wireless system planning, radio communications, and ensuring compliance with regulations.
