Your antenna tuner becomes inoperative. How can you obtain operation on both 8 MHz and 22 MHz frequency bands?

By bypassing the antenna tuner and using a straight whip or wire antenna approximately 30 ft long, you effectively allow for a broader range of frequencies to be used without the tuner’s impedance matching capabilities. A straight wire antenna can resonate well at multiple frequencies, particularly in the HF range, allowing for effective radiation at both 8 MHz and 22 MHz.

Shortening the antenna to 15 ft, as suggested in one of the options, would likely reduce its effectiveness in covering those frequencies. A length of around 30 ft is closer to a half-wave for 22 MHz, which enhances its ability to transmit and receive on that band effectively while still offering acceptable performance on the lower 8 MHz band. This method leverages the natural characteristics of the antenna and the frequency bands involved, proving a practical solution when tuning equipment is unavailable.
