← ScienceWhich risk increases when an antenna's gain is maximized?
A)Signal interference becomes directional✓
B)Bandwidth availability is limited
C)Power consumption overwhelms circuit
D)Electromagnetic wave front refraction
💡 Explanation
Maximizing antenna gain narrows the beamwidth, increasing the risk of directional signal interference, because the antenna is more sensitive to signals from a specific direction due to increased constructive Interference; therefore, undesired signals arriving from that narrow field are amplified rather than broadly distributed, leading to interference.
