As others have stated I am sure that VA6AM can make a 80/40 duplexer for you
however the easiest approach would be to just run another feedline to your
fan dipole.

I'm investigating upgrading my station from its present 500W capability
to 1500W. I've located sources for most of the up-rated bandpass filters
and other hardware required for the project, but can't seem to find a
source for a duplexer to split a 80-40 dipole for SO2R use. I'm
presently using one of the Low Band Systems 500W 80/40/20 triplexers for
this function. LBS apparently makes a 1500W 80/40 duplexer, but it
appears the LBS stuff is no longer available in the USA. Does anyone
have or know of a suitable 1500W unit? I do NOT need it to be rated for
100% duty cycle since I'm only interested in CW and occasional SSB use,
but it needs to hold up under contest conditions with a full power
amplifier.
4O3A makes a nice 20/15/10 triplexer, but they don't have any high power
80/40 units. Antennas-Amplifiers (distributed by DX Engineering) makes
nice HP bandpass filters, but not a triplexer or duplexer. VA6AM (also
distributed by DX Engineering) doesn't have any high power devices.
