Which outcome occurs when an EMP impacts a long-distance HF radio antenna?

A)Differential mode current surges occur.
B)Increased SWR due to impedance mismatch
C)Antenna gain pattern deformation results.
D)Reduced efficiency via ground losses.

💡 Explanation

An EMP induces strong currents due to Electromagnetic Induction because magnetic fields rapidly change, therefore differential mode current surges are generated along the antenna length, overwhelming any protection, rather than affecting SWR or gain patterns primarily.
