Question:
Frequencies in the UHF range normally propagate by means of:
Frequencies in the UHF range normally propagate by means of:
Show Hint
UHF and VHF bands propagate via **space waves** — ideal for line-of-sight communications like TV and mobile.
Updated On: May 20, 2025
- Space waves
- Surface waves
- Ground waves
- Sky waves
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
UHF (Ultra High Frequency) range lies between \( 300\, \text{MHz} \) and \( 3\, \text{GHz} \). These frequencies cannot reflect from the ionosphere and are not suitable for ground wave propagation due to high attenuation.
They are best suited for:
- Line-of-sight communication
- Television broadcast
- Satellite communication
- Mobile phones
Hence, they propagate via space waves — which travel directly from the transmitter to receiver.
