Calculator
Formula
Total loss dB = cable length × loss per 100 m / 100
Notes
Use this calculator as a first estimate. Real RF results depend on antenna placement, ground plane, connectors, cable routing and measurement conditions.
Estimate coax cable attenuation by length and loss per 100 meters.

No. They are estimates and should be verified with measurements.
PCB layout, cables, connectors, antenna placement and nearby objects affect RF performance.
