Thanks for the answer Weak AM.
I live in a remote area. The clossess house is at about 4 km. I am not specialy looking for range, just to be abble to use an old tubes radio that goes up to 1580 kHz, but at night, this upper range of the MW band is pretty crowded. On the other hand, I have good spots free all time on the LW band.
The antenna could be an external LC circuit like this one : http://www.imagenisp.ca/jsm/loop.html
