No, an earth antenna radiates in the direction of the wire,
approximately east-west...

I agree.
Best would be a stony mountain sourrounded by a small lake rivulet. For
example like here:

Ah and BTW it would be good to have a good Restaurant near that
location, just to spend a few hours there while transmitting.
Sharing some of my thoughts... :-)
