  1. Reflection
  2. Refraction
  3. Scattering
  4. Warping
Correct answer: B
Question 2

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