Directional Antenna
Focused radio beams cut through interference to extend communication range
2 days ago

Why are directional antennas preferred over omnidirectional antennas in point-to-point communication?
Because they concentrate radio waves in a specific direction, increasing signal strength and reducing interference.
Because they broadcast signals evenly in all directions to cover more area.
Because they randomly change direction to avoid interference.

Why must a parabolic antenna's reflector be much larger than the wavelength of the radio waves it handles?
Because larger reflectors are easier to manufacture regardless of wavelength.
To achieve a narrow beamwidth and high directivity by effectively focusing the radio waves.
To amplify the radio waves through the size of the reflector alone.
