SCTE MT1 Coaxial cable Exam
Questions and Answers
Name the component that protects and prevents EMI and RFI in a coax circuit. - Answer-Shield
Reflections are caused by: - Answer-improper connector terminations in the HFC resulting in an
impedance mismatch
A guideline for bending radius is _____ times cable diameter. - Answer-10, ten
A break in the coax shield allowing signals to leak out is called: - Answer-egress
A section of coaxial cable is 75 feet long feeding a 4-way splitter at the customer location. Assume that
the coaxial cable has an attenuation of 1.8 dB per hundred feet at 200 MHz. What would be the
approximate dB attenuation at the splitter's output port at 200 MHz? - Answer-8.35
Which of the following are components of the coaxial cable which will affect its impedance properties?
(choose 3) - Answer-inner diameter of the shield, outer diameter of the center conductor, type of
dielectric material
True or False: Coaxial cable attenuation has a flat loss across all frequencies. - Answer-False
