NameTypeDescription
CharacteristicImpedance P_SINGLEVALUE / IfcElectricResistanceMeasure A quantity defined for a mode of propagation at a given frequency in a specific uniform transmission line or uniform waveguide by one of the three following relations: Z1 = S/ |I|2 Z2 = |U|2 / S Z3 = U / I where Z is the complex characteristic impedance, S the complex power and U and I are the values, usually complex, respectively of a voltage and a current conventionally defined for each type of mode by analogy with transmission line equations
CouplingLoss P_SINGLEVALUE / IfcNormalisedRatioMeasure Indicates the coupling loss of a leaky coaxial cable (radiating cable).
MaximumTransmissionAttenuation P_SINGLEVALUE / IfcSoundPowerLevelMeasure Indicates the Maximum transmission attenuation of feeder.
NumberOfCoaxialPairs P_SINGLEVALUE / IfcCountMeasure Indicates the total number of coaxial pairs in the coaxial cable.
PropagationSpeedCoefficient P_SINGLEVALUE / IfcRatioMeasure Indicates the propagation speed coefficient.
TransmissionLoss P_SINGLEVALUE / IfcNormalisedRatioMeasure Indicates the transmission loss of the leaky coaxial cable (radiating cable).
RadiantFrequency P_SINGLEVALUE / IfcFrequencyMeasure Indicates the radiant frequency of the leaky coaxial cable (radiating cable).
