Certified Ethical Hacker (CEH v11) — Question 259

Which of the following antennas is commonly used in communications for a frequency band of 10 MHz to VHF and UHF?

Answer options

Correct answer: A

Explanation

The Yagi antenna is well-suited for the specified frequency range, providing directionality and gain, making it effective for communication purposes. While Dipole and Omnidirectional antennas can operate within these frequencies, they do not offer the same performance characteristics for this specific range as the Yagi does. The Parabolic grid antenna is typically used for higher frequency applications, such as microwave communications, rather than the VHF and UHF bands.
