No, "couteracting" the resistance in the entire antenna.  It's an antenna 
(TC secondary) effect.  It's a negative resistance feed back to the entire 
secondary.  Not, just a feed back to the switch in a CW coil.

One of the factors that limits antenna current is the ohmic resistance of 
the tuned detector tank circuit and the antenna wire itself.  Regeneration 
is a means of increasing antenna current by counteracting the resistance of 
the entire antenna circuit.  By the introduction of what might be called 
negative resistance through the addition of a feedback loop, antenna-field 
interaction is increased and energy is absorbed from a greater area of the 
incoming wave front.
