You should use a Q2330E Sinclair duplexer for less loss at 600Khz separation or the Q2220E set at the higher insertion loss to get the deeper notches.
There was a re-entrant version of the Q2330E called the Q2332E which is shorter but should be mounted in something to protect both ends of the filter if it is to be moved around allot. I once made a re-entrant short VHF 600KHz split duplexer out of PC Boards from the design publish in QST about 27 years ago but that had about 3 dB loss and was fragile.
