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

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

Selected Answer: A
A is correct. 7. Beamwidth is measured at the points where the main lobe decreases in power by 3 dB. The horizontal beamwidth is typically shown on the Azimuth chart and the vertical beamwidth is shown on the Elevation chart. When the gain of an antenna increases, the beamwidth decreases. When the beamwidth increases, the gain decreases.
