Your antenna tuner becomes totally inoperative. What would you do to obtain operation on 2 HF bands?

Correct Answer: Option D — Bypass the antenna tuner. Use a straight whip or wire antenna approximately 30 ft long.

If an automatic antenna tuner fails, the transmitter cannot match its output impedance to the antenna. Using a wire approximately 30 feet long provides a compromise length that may allow for limited operation on specific HF bands by presenting a manageable impedance to the transmitter's final output stage.
