Question 2

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

Select an option, then click Submit answer.

  • ○

    Horizontal and vertical beamwidth are calculated at the point where the main lobe decreases power by 3 dB.
  • ○

    Vertical beamwidth is displayed (in degrees) on the antenna’s Azimuth chart.
  • ○

    When antenna gain is lower, the beamwidth is also lower in both the horizontal and vertical dimensions.
  • ○

    The beamwidth patterns on an antenna polar chart indicate the point at which the RF signal stops propagating.
Question 3

What is an advantage of using WPA2-Personal instead of WEP-128 as a security solution for 802.11 networks?

Select an option, then click Submit answer.
