Where should an RF wattmeter be connected for the most accurate readings of transmitter output power?
- A At the antenna feed point
- B At the transmitter output connector
- C One-half wavelength from the transmitter output
- D One-half wavelength from the antenna feed point
Correct answer: B — At the transmitter output connector. From the official ISED question bank, verified word for word.
Why
Connecting the RF wattmeter directly at the transmitter output connector ensures you measure the power the radio actually generates before any loss occurs in the cable. The full explanation — and one for every question — is in Pro.
