When selecting an accessory SWR meter, what should be considered?

• A. The brand of the meter
• B. The frequency and power level for measurements
• C. The color of the meter
• D. The size of the installation

Answer: (B)

When selecting an accessory SWR (Standing Wave Ratio) meter, it is crucial to consider the frequency and power level for measurements. This is because SWR meters are frequency-dependent devices that need to be compatible with the specific bands you plan to operate on. Different meters are designed to cover various frequency ranges, so choosing one that matches your operating frequencies is essential to ensure accuracy in measuring the SWR, which can help you avoid issues like reflected power that could damage your equipment or reduce transmission efficiency.

Additionally, the power level ranges that the meter can handle must align with your transmitter's output power. Using a meter that cannot measure the power levels you intend to use may lead to inaccurate readings or even damage to the meter. Therefore, confirming these specifications ensures that the SWR meter will be effective and reliable for your intended applications.
