PW0-105 · Question #46
What statements about the beamwidth of an RF antenna are true? (Choose two)
The correct answer is C. Horizontal and vertical beamwidth are calculated at the points in which the main lobe decreases power by 3 dB. D. Horizontal beamwidth is displayed (in degrees) on the antenna's Azimuth Chart. See the full explanation below for the reasoning.
Question
What statements about the beamwidth of an RF antenna are true? (Choose two)
Options
- AThe lower the gain of an antenna, the more narrow one or both beamwidths become.
- BThe beamwidth patterns on an antenna polar chart indicate the point at which the RF signal stops propagating.
- CHorizontal and vertical beamwidth are calculated at the points in which the main lobe decreases power by 3 dB.
- DHorizontal beamwidth is displayed (in degrees) on the antenna's Azimuth Chart.
- EAntenna beamwidth is measured in units of decibels relative to an isotropic radiator (dBi).
