Question 1 of 27070

There is an improper impedance match between a 30 watt transmitter and the antenna, with 5 watts reflected. How much power is actually radiated?

🔍 Key Concepts

• Forward power vs. reflected power in a transmitter-antenna system • Basic power relationship: Transmitted power = Forward power − Reflected power (when considering only these two values) • What improper impedance match does to effective radiated power

💭 Think About

• If 30 watts is leaving the transmitter but 5 watts is reflected back, what happens to the remaining power? • Which choice best represents the net power actually going out through the antenna after subtracting what is reflected? • Does reflected power add to, subtract from, or have no effect on the power that is actually radiated?

✅ Before You Answer

• Be clear on which value is total output from the transmitter and which value is reflected back. • Confirm that reflected power does not increase radiated power; it represents loss or mismatch. • Before picking an answer, explicitly compute: Net radiated power = forward (transmitter) power − reflected power and compare that result to the options.
