What is a disadvantage of the "rubber duck" antenna supplied with most handheld radio transceivers?

It requires external power
It does not transmit or receive as effectively as a full-sized antenna
It can only operate on one frequency
It is extremely heavy and impractical

The correct answer is: It does not transmit or receive as effectively as a full-sized antenna

The "rubber duck" antenna, commonly supplied with handheld radio transceivers, is typically a compact, portable antenna designed to enhance the convenience of using portable radio equipment. However, one of its main disadvantages is that it does not transmit or receive as effectively as a full-sized antenna. The effectiveness of an antenna is often influenced by its size, design, and the wavelength of the signals being transmitted or received. A full-sized antenna, being larger, can capture more signal and radiate more power compared to a smaller antenna like the rubber duck. This size difference can lead to lower gain and poorer performance, especially in terms of range and signal clarity. Users may notice that while the rubber duck antenna is convenient, it may not provide the same level of communication quality or distance as more robust antenna options. In contrast, the other options present characteristics that do not align with the functionality of a rubber duck antenna. It does not require external power, can operate on multiple frequencies, and is generally designed to be lightweight and practical for portable use.
