How does the total amount of radiation emitted by a directional gain antenna compare with the total amount of radiation emitted from a theoretical isotropic antenna, assuming each is driven by the same amount of power?

  1. The total amount of radiation from the directional antenna is increased by the gain of the antenna
  2. The total amount of radiation from the directional antenna is stronger by its front-to-back ratio
  3. They are the same
  4. The radiation from the isotropic antenna is 2.15 dB stronger than that from the directional antenna
