  • Question

  • A transmission line is feeding 1 watt of power to a horn antenna having a gain of 10 dB. The antenna is matched to the transmission line. The total power radiated by the horn antenna into the free space is


  • Options
  • A. 10 watts
  • B. 1 watt
  • C. 0.1 watt
  • D. 0.01 watt

  • Correct Answer
  • 10 watts 

    Explanation
    A transmission line is feeding 1 watt of power to a horn antenna having a gain of 10 dB. The antenna = 101 ⟹ Pr = 10 watt.
