How does increasing transmitter power influence radio wave coverage area?

• A. It restricts coverage area
• B. It has no effect on coverage
• C. It can increase the coverage area
• D. It only affects signal quality

Answer: (C)

Increasing transmitter power generally enhances the coverage area of radio waves. When the transmitter power is boosted, the energy emitted from the antenna increases, allowing the radio waves to travel farther. This means that a greater distance can be covered, effectively extending the range at which receivers can detect the transmitted signals. Additionally, higher power levels can help overcome obstacles, such as hills or buildings, which may otherwise attenuate the signal. As a result, more users in a larger geographic area can access the radio signal, thus improving the overall effectiveness of the transmission. While it is important to note that increasing power does not guarantee improved coverage in every situation—due to factors such as frequency used, terrain, and environmental conditions—generally, a higher power output leads to an increase in the coverage area provided that other conditions are favorable.
