Hi Francesco and all,
IMHO the antenna employs the braids of the twin coaxes as a
counterpoise, i.e. the missing dipole arm. If both the boxes were
placed tightly adjacent to each other with no grounding and the
outgoing (single) coax was equipped with a RF choke, the antenna would
be probably quite poor.
