Attenuation, power & cable-length estimator
Cable-only attenuation is stated at 25°C in dB/100 m. Power-reference values are from the catalogue at 40°C ambient, sea level, VSWR 1.1.
Estimate insertion loss for your cable length
Cable-only loss = (published attenuation in dB/100 m) × (length in metres / 100). Excludes connectors and mismatch; uses only published frequency points, with no interpolation or extrapolation.
