How about a little more explanatin on the 50% reradiates?


In a perfectly matched system, half the power is "lost"
in the source. In the case of a receiving antenna, that
power is lost to radiation from the antenna during
receive, i.e. the antenna radiation resistance is the
"source".

Something I have wondered about: If we simply amplify
the receiver voltage through a near infinite impedance
FET with virtually no load on the signal, do we get the
signal information but lose virtually all the power to
re-radiation? (assume high S/S+N)
