# Coax impedance and attenuation estimate
# Scope: Cable loss at supplied per-length attenuation; connectors included separately.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

length = 5 m
attenuationPerMetre = 0.2 m^-1
connectorLossDb = 1

lossDb := attenuationPerMetre*length+connectorLossDb
powerFraction := 10^(-lossDb/10)

check loss budget in dB: lossDb <= 3

scenario alternative: length = 4 m
