SUMMARY

The discussion centers on the omission of the transmitted antenna gain (Gt) in the solution to a homework problem involving the Friis transmission equation. The equation, Pr(db) = Pt + Gt + Gr - Lp, clearly includes Gt, which raises questions about the accuracy of the provided solution. Participants agree that the absence of Gt is likely an error, indicating the importance of considering all components in antenna gain calculations.

This looks like an error to me, too.
