Propagation Measurement on 2.5 mm NYAF Cable Using Load Matching and TDA

Abstract

In this work, we propose measuring the propagation speed on the transmission medium in the form of a 2.5mm NYAF cable. The method used is load matching and time difference of arrival (TDA). The load matching method uses the same load as the characteristic impedance of the cable. While the TDA method measures two points on the cable with a capacitive load on the output side. From the results of the study, it was found that on the load impedance method, the average propagation speed on a 2.5mm NYAF cable is 1.9 × 108 m»s or 0.63 c. Meanwhile, in the time difference of arrival (TDA) method, the average propagation speed on a 2.5mm NYAF cable is 0.5 × 108 m»s or 0.17 c.
