"How about a little more explanation on the 50% reradiation?"

The antenna doesn`t care where the power comes from. It can be from
connected drive or induced. Induced power has two loads, radiation
resistance and connected load (receiver input). If they are matched
(equal), 50% is absorbed in each.

If they are mismatched, paximum power transfer can`t occur. A higher
percentage of the available energy will be rejected or reradiated
because the receiver input is nearer to an open circuit (rejection) or a
short circuit (reradiation) than it is when it is matched to the
antenna`s radiation resistance.
