[Elecraft] RxAnt?

[Don Wilhelm]

Jim,

That is correct - and you can confirm from the schematic if you like. 
The receive antenna is connected on the same side of the T-R switch as 
the PA transistor output.  (the receive antenna is injected at the same 
place the W1 jumper is placed in a K2 without the K160RX option.)

The receive antenna does not travel through the Low Pass Filter as the 
normal antenna connection does, but then a low pass filter is not needed 
  on receive anyway, the bandpass filter provides all the per band 
selectivity needed.

73,
