← ScienceWhich mechanism causes reduced radio transmission range when a high-voltage transmission line experiences corona discharge near a broadcasting antenna?
A)Capacitive interference absorbs signal energy✓
B)Thermionic emission degrades antenna gain
C)Inductive coupling boosts signal noise
D)Resistive losses diminish radiation efficiency
💡 Explanation
Capacitive interference reduces transmission range because the corona discharge creates ionized air, increasing the capacitance between the power line and antenna; therefore radio signal energy shunts to the power line, rather than propagating freely.
