Exam 312-50v13 Topic 1 Question 52 Discussion

In CEH v13 Module 11: Hacking Wireless Networks, antenna types are critical for wireless communications, signal strength, and attack range.
Yagi Antenna
A directional antenna designed to operate in VHF (30 MHz to 300 MHz) and UHF (300 MHz to 3 GHz) frequency bands.
Frequently used for point-to-point communication, such as long-distance Wi-Fi or directional signal monitoring.
Offers high gain, narrow beamwidth, and works well for capturing or projecting signals over long distances.
Why Other Options Are Incorrect:
B). Dipole antenna: Typically omnidirectional; less gain; not optimized for long-distance VHF/UHF.
C). Parabolic grid antenna: Used in microwave and satellite frequencies; not suited for 10 MHz-VHF.
D). Omnidirectional antenna: Broadcasts in all directions; used in short-range access points.
