Default Poynting vector

Father of the famous vector wrote in 1884 (before the Hertz experiment):
"The whole of the energy then enters in through the external surface of the
wire, and by the general theorem the amount entering in must just account
for the heat developed owing to the resistance,"

A few days ago Jimp wrote:
"An antenna is a device that converts the AC electrical energy at it's
terminals into electromagnetic energy which radiates from the antenna".

So "enters in = radiates from"?
Can anybody help?
