[TowerTalk] Cushcraft D3W SWR Issue

[Gene Smar]

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.
