🔍 Key Concepts

• Function of an antenna coupler/tuner in an HF marine radiotelephone system • Typical physical lengths of HF whip or wire antennas used on small vessels • How antenna length relates to wavelength (and thus frequency bands)

💭 Think About

• Which option, if any, still allows you to radiate a signal at all, even with a failed tuner? • Compare the physical antenna lengths mentioned with the wavelengths used in common marine HF bands—does a shorter or longer antenna give you more usable bands without tuning? • Does any choice describe a practical, emergency‑usable compromise length that can work tolerably on more than one HF band without a tuner?

✅ Before You Answer

• Eliminate any option that claims transmission is completely impossible without a tuner—think about basic wire antennas. • Check which proposed antenna length (15 ft vs ~30 ft) more closely matches a reasonable fraction of a wavelength for common marine HF bands (3–30 MHz). • Confirm that the selected option involves bypassing the failed coupler/tuner and using a simple, resonant‑enough antenna rather than relying on broken equipment.

Question 1 of 20

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

Without an operating antenna coupler/tuner, transmission is impossible.

It is impossible to obtain operation on 2 different HF bands, without an operating antenna coupler/tuner.

Bypass the antenna coupler/tuner and shorten the whip to 15 ft.

Bypass the antenna coupler/tuner. Use a straight whip or wire antenna approximately 30 ft long .
