That would be a diplexer, not a duplexer.

http://www.datacomm.ch/hb9abx/duplexer.html

There *used to be* a very, very good design, easily build and readily repeatable, on that site.
It appears that the site owner has had a hissy-fit over criticism of a "magical antenna" design, and has pulled it down.  A spot of googling will turn up a copy of the original article, though, which I won't link to directly just in case HB9ABX gets even more upset.  Alternatively you could email him and see if he'll sell you a copy.

Nothing is ever entirely deleted from the Internet.  Nothing.
