Measuring the amount of crosstalk in the UAV is necessary to ensure that the system and equipment on the onboard UAV can be operated properly without any Electromagnetic Interference (EMI). This paper was conducted to determine the effect of interference in the UAV cabling system by measuring EM crosstalk between the cables. Variations in the type of cables and the distance between the transmitting and receiving cables are carried out to analyze the relationship between the magnitude of the induced voltage on the receiving cable. The results of the experiments that have been measured, it is found that the use of coaxial cable is the best in reducing EMI. In addition, a distance between transmitting and receiver cables of more than 4 cm can suppress EMI by almost 60%.
