It is 1.3 meter from the curtain. the angle is the same, cause I
have the triangular antenna. Possible explanation also : the
curtain is not regularly folded, there are not in fact nice folds,  
it is stretched (1.70m width out of a curtain width measure of 2.5m
to give an idea).

It's interesting once again what you say about the curtain. The mast
frequency I pick is the GSM around 900 Mhz.

I'll do more tests later.
