SBCA Signal Distribution 2

Question 1

In a satellite signal distribution system, what is the primary purpose of a splitter?

Accepted Answer

Divide one input signal into multiple output signals

Answer

A splitter divides one input signal into multiple output signals, allowing a single source to feed several receivers simultaneously.

Question 2

Which type of cable is most commonly used for satellite signal distribution in residential installations?

Accepted Answer

RG-6 coaxial cable

Answer

RG-6 coaxial cable is the standard for residential satellite installations due to its lower signal loss at satellite frequencies compared to RG-59.

Question 3

What does a multiswitch accomplish in a satellite distribution system?

Accepted Answer

It allows multiple receivers to access multiple satellite transponders

Answer

A multiswitch allows multiple satellite receivers to independently select from multiple satellite feeds and transponders.

Question 4

What is the typical impedance of coaxial cable used in satellite signal distribution?

Accepted Answer

75 ohms

Answer

Satellite and cable TV distribution systems use 75-ohm coaxial cable as the standard impedance.

Question 5

When cascading amplifiers in a distribution system, which problem becomes a primary concern?

Accepted Answer

Noise accumulation

Answer

Each amplifier in a cascade adds its own noise figure, causing cumulative noise accumulation that degrades signal quality.
