← ScienceWhich consequence results when multiple radio antennas transmit identical signals?
A)Directional signal strength amplification✓
B)Frequency spectrum bandwidth broadening
C)Reduced signal-to-noise ratio system-wide
D)Complete signal phase randomization
💡 Explanation
Directional signal amplification happens because constructive and destructive interference affect signal strength based on relative path lengths to the antennas. Path length differences cause constructive interference in specific directions, therefore increasing signal strength, rather than randomizing the entire signal.
