Question
Which of the following antennas is commonly used in communications for a frequency band of 10 MHz to VHF and UHF?
Options
- AYagi antenna
- BDipole antenna
- CParabolic grid antenna
- DOmnidirectional antenna
Explanation
Yagi antennas are commonly used for directional communication across a broad frequency range from 10 MHz to VHF and UHF bands.
Common mistakes.
- B. Dipole antennas are fundamental and versatile, but they are generally less directional and efficient than Yagi antennas for specific directional applications in the higher parts of the VHF/UHF range.
- C. Parabolic grid antennas are highly directional and are primarily used for microwave and higher frequency bands (typically several GHz) for long-distance communication, not commonly for 10 MHz up to UHF.
- D. Omnidirectional antennas radiate equally in all directions and are used for general coverage, but they are not the common choice for directional communication within the specified frequency range where a Yagi would excel.
