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.

Which directional antenna types are commonly used by indoor Wi-Fi devices in a MIMO multiple spatial stream implementation?

  1. Dish and grid
  2. Dipole and yagi
  3. Grid and sector
  4. Patch and panel

Answer(s): D



What statement about the beamwidth of an RF antenna is true?

  1. Horizontal and vertical beamwidth are calculated at the point where the main lobe decreases power by 3 dB.
  2. Vertical beamwidth is displayed (in degrees) on the antenna’s Azimuth chart.
  3. When antenna gain is lower, the beamwidth is also lower in both the horizontal and vertical dimensions.
  4. The beamwidth patterns on an antenna polar chart indicate the point at which the RF signal stops propagating.

Answer(s): A
