| Feb 6, 2018 at 20:29 | comment | added | JSH | I'll just add to the answers here that the lambda term is in there simply because Friis defined it that way during his attempt to suggest another way to express antenna gain... en.wikipedia.org/wiki/… | |

| May 28, 2017 at 22:11 | comment | added | Scott Earle♦ | I know, but I was referring to the recent conversation in meta about using dB and not watts, and it just makes sense to be consistent :) | |
| May 28, 2017 at 16:44 | comment | added | Phil Frost - W8II | @ScottEarle 1 = 0dB (dBi if you want to be more specific) because $10^{0/10} = 1$. | |
| May 28, 2017 at 14:46 | comment | added | Scott Earle♦ | Is the gain 1 or is it 0dB? I thought we recently had this discussion | |
| May 26, 2017 at 18:27 | comment | added | Phil Frost - W8II | @MikeWaters Sure it does. The gain is 1, by definition of "isotropic antenna". | |
| May 26, 2017 at 18:19 | comment | added | Mike Waters | The first formula does not take gain into account. | |
