Which of the following causes failure of coaxial cables?
Moisture contamination✓پاسخ درست
Solder flux contamination
Rapid fluctuation in transmitter output power
Operation at 100% duty cycle for an extended period
توضیح
Water entering coaxial cable through cracked jackets, unsealed connectors or a damaged end wicks along the braid and dielectric, raising loss and corroding the conductors, and it is the classic cause of cable failure. Rosin flux is non-corrosive, and coax is not damaged by normal duty cycle or power variation within its ratings.
