Where should an RF power meter be installed?

• A. In the feed line, between the transmitter and antenna
• B. At the output of the antenna
• C. Near the power supply
• D. At the transceiver output terminal

Answer: (A)

An RF power meter should be installed in the feed line, between the transmitter and the antenna. This location is ideal because it allows for accurate measurement of the power being transmitted into the antenna system. By placing the meter in the feed line, it can provide valuable insights into the efficiency of the transmitter and the performance of the antenna. This is crucial for ensuring that the system is operating within the desired power levels and for troubleshooting any potential issues that may arise in the transmission path. Installing the meter at the output of the antenna would not provide an accurate measurement of transmitted power, as it wouldn't account for losses that may occur in the feed line itself. Furthermore, placing the meter near the power supply or at the transceiver output terminal would also fail to measure the effective power reaching the antenna. The primary goal is to assess how much power actually reaches the antenna for radiation, making the feed line position the most practical and effective choice.
