Understanding PL-259 Coax Connectors

Which of the following is true of PL-259 type coax connectors?

They are preferred for microwave operation

This answer is incorrect because PL-259 connectors are not designed for microwave frequencies; they are better suited for lower frequencies like HF and VHF.

They are watertight

This answer is incorrect because PL-259 connectors are not inherently watertight and usually require additional weatherproofing for outdoor use.

They are commonly used at HF and VHF frequencies

This answer is correct because PL-259 connectors are commonly used at HF and VHF frequencies due to their compatibility and performance within these ranges.

They are a bayonet-type connector

This answer is incorrect because PL-259 connectors use a threaded coupling mechanism rather than a bayonet-type design.

Explanation

PL-259 type coax connectors are widely recognized and used in amateur radio, particularly at HF (High Frequency) and VHF (Very High Frequency) bands. These connectors are appreciated for their robustness and reliability in various applications. The significance of this question lies in understanding the practical applications and limitations of different coaxial connectors used in radio communications. The PL-259 connectors, also known as UHF connectors, operate efficiently within the HF (3-30 MHz) and VHF (30-300 MHz) ranges. This makes them a popular choice for general amateur radio use, making them readily available and cost-effective. Knowing the appropriate use of these connectors ensures effective and efficient radio communication, which is crucial for both casual and emergency use.
