How far will the daylight groud wave go with 1kw
from the stick on 120 meters and what are the best trnsmitting aerials?


Grateful for info


The question is a little open ended. Theoretically the answer is forever
but you probably mean how far away can you have a usable signal.

You only stated the transmit power but you have to consider the path
losses and also the frequency. Generally in order to reduce ground
losses the signal should be vertically polarized. The distance will
improve when both the transmit and receive antennas are higher off the
ground.
