Which consequence results when a submarine's ultra-low frequency transmitter faces impedance mismatches?

💡 Explanation

Reduced antenna radiation efficiency occurs because reflection from impedance mismatches decreases emitted power, the mechanism involved being wave reflection; therefore, radiation efficiency suffers rather than increased drag, corrosion, or navigation errors.
