What is the effective radiated power of a repeater with 100 watts transmitter power output and specified losses?

• A. 90 watts
• B. 100 watts
• C. 110 watts
• D. 80 watts

Answer: (B)

The effective radiated power (ERP) of a repeater is determined by taking into account the transmitter power output and any losses that occur in the system, such as those from cables, connectors, or antennas. In this scenario, if the transmitter power output is 100 watts and there are no significant losses indicated, then the effective radiated power remains at 100 watts. When losses are considered, ERP can decrease, but if the question does not specify any losses in this case, then the effective radiated power would indeed be equal to the transmitter power output, resulting in 100 watts. This reflects the concept that effective radiated power is a measure of the actual power that is radiated by the antenna, taking into account both the transmitter output and any losses along the transmission path. Hence, under the given conditions, the effective radiated power is accurately assessed as 100 watts.
