Your antenna tuner becomes totally inoperative. What would you do to obtain operation on both the 8 MHz and 22 MHz frequency bands?

• A. Repair the tuner
• B. Replace the radio
• C. Bypass the antenna tuner. Use a straight whip or wire antenna approximately 30 ft long
• D. Relocate the antenna

Answer: (C)

When the antenna tuner fails, its job to match the transmitter to the antenna across different frequencies is lost. The quickest way to stay on the air is to bypass the tuner and feed a simple, non-tuned radiator directly. A straight whip or long wire about 30 feet long is a practical choice because it is roughly a quarter-wavelength on the 8 MHz (40-meter) band, giving a reasonably resonant radiator for that band, while still radiating on the higher 22 MHz band without the tuner. This lets you operate on both frequencies without waiting to repair or replace equipment.

Repairing or replacing the radio would restore proper tuning, but in the meantime the bypass method provides immediate, workable operation. Relocating the antenna could help with impedance, but it won’t restore the tuner’s function, and the 30-foot straight antenna is a straightforward, widely used fallback.
