What is a disadvantage of the short, flexible antenna supplied with most handheld radio transceivers?

• A. It has low efficiency
• B. It requires a power amplifier
• C. It is difficult to transport
• D. It can only receive signals

Answer: (A)

The short, flexible antenna that typically comes with most handheld radio transceivers is designed for portability and convenience, which is advantageous for users on the go. However, one of the significant drawbacks of this type of antenna is its low efficiency.

The efficiency of an antenna relates to how well it can convert the electrical energy from the radio transceiver into radio waves. Short antennas, like the flexible ones provided with handheld radios, are often limited in their ability to effectively radiate or receive radio frequency signals, particularly at various frequencies. This means that while they are easy to carry and do offer some level of performance, they may not perform as well as longer, fixed antennas which can provide better range and clarity in communication. Therefore, in terms of overall communication effectiveness, a low-efficiency antenna does not transmit signals as well as a higher-efficiency option would, making it a disadvantage in many operating situations.
