I'll third that...even though duplexers are typically reactive, if it's right, length of the cables should not be an issue.
If it is, I would look at either the duplexer or the antenna/feedline. As always, put a dummy load after the duplexer and see if all is well. If it is, it's an antenna system problem. If not, it's a duplexer problem. (barring repeater internal problems...) -- Jim Barbour WD8CHL Steve S.
