Demo Questions
Question 1
An RF signal sometimes bends as it passes through some material other than free space. What is the term that describes this behavior?
- Reflection
- Refraction
- Scattering
- Warping
Correct answer: B
Question 2
What can an impedance mismatch in the RF cables and connectors cause?
- Fewer MCS values in the MCS table
- Excessive VSWR
- Increased amplitude of the RF signal
- Increased range of the RF signal
Correct answer: B

Question 3
In a long-distance RF link, which statement about Fade Margin is true?
- The Fade Margin is a measurement of signal loss through free space and is a function of frequency and distance.
- The Fade Margin of a long-distance radio link should be equivalent to the receiver’s low noise filter gain.
- A Fade Margin is unnecessary on a long-distance RF link if more than 80% of
- Fade Margin is an additional pad of signal strength designed into the RF system to compensate for unpredictable signal fading.
Correct answer: D
