In Europe, the RF signal is applied in differential mode between the two
power conductors (neutral, which may be grounded in various different
ways or not grounded at all) and line 230 V 50 Hz). It stays
substantially differential for oh, about 10 m or so! Beyond that, the
cables radiate - ALL of the cables. So the field pattern, inside, and
even immediately outside, a dwelling, is fearfully complex. This
applies, of course, regardless of whether the inhabitants subscribe to
the BPL service or not.

An excellent resumé.
