Question 5

In a long-distance RF link, what statement about Fade Margin is true?

A Fade Margin is unnecessary on a long-distance RF link if more than 80% of the first Fresnel zone is clear of obstructions.

The Fade Margin is a measurement of signal loss through free space and is a function of frequency and distance.

Fade Margin is an additional pad of signal strength designed into the RF system to compensate for unpredictable signal fading.

The Fade Margin of a long-distance radio link should be equivalent to the receiver's low noise filter gain.

Correct Answer: C

Fade Margin is an additional pad of signal strength designed into the RF system to compensate for unpredictable signal fading. This ensures that the RF link remains reliable despite potential variations in signal strength due to environmental factors or other unpredictable conditions.

C. Fade Margin is an additional pad of signal strength designed into the RF system to compensate for unpredictable signal fading. CHAPTER 3 - PAGE 111 (Official Study Guide) "The extra signal strength actually has a name and is FADE MARGIN." "The Fade Margin will give you two things: a more consistent link and a longer lasting link."
