Serge:
If after you inspect the D3W you determine that the Y-split in the coax
is the culprit, I described a method of sealing this split at
http://lists.contesting.com/archives//html/Towertalk/2002-10/msg00391.html .
As I wrote here before, it's not my idea but works well so far (since 2001)
in sealing my balun connections.
