What are the four components of a coaxial cable? - The components are the inner conductor,
insulator, braided mesh conductor, and sheath. Each part plays a role in carrying data, insulation,
grounding, or protection.
What is the purpose of the inner conductor in coaxial cable? - The inner conductor carries the
data signals. It is made of a copper core.
What material surrounds the inner conductor, and what does it do? - The insulator surrounds the
inner conductor to keep the signal separated from the mesh. It is made of PVC plastic.
What is the function of the braided mesh conductor in coaxial cable? - It serves as a second
physical channel and functions as the ground. It is typically made of aluminum or tin-coated
copper.
What material is used for the sheath in coaxial cable and what is its purpose? - The sheath is
made of PVC plastic. It encases and protects the entire cable from external elements.
What are three advantages of coaxial cable over other cable types? - It is less susceptible to
electromagnetic interference (EMI), is resistant to physical damage, and has a large existing
infrastructure.
What are three disadvantages of coaxial cable compared to other cable types? - It is expensive,
not very flexible (hard to bend around corners), and using multiple splitters can degrade signal
quality.
What is the resistance rating of RG-59 coaxial cable? - RG-59 has a resistance rating of 75 ohms.
It is used in CCTV video systems and for short cable TV runs under 3 meters.
What is the resistance rating of RG-6 coaxial cable? - RG-6 also has a 75 ohm rating. It is used
for cable TV, satellite TV, and broadband cable internet.
