I want to use a common feedline (RG8) with two antennas, one 10 - 40 meters, the other 80 meters. Does someone make a duplexer for these frequencies? What would be the proper way to accomplish this?

I think a cheaper and easier way to accomplish this is to use a remote coax cable switch...you can find examples of this in the ARRL handbook or buy commercial ones from various amateur radio suppliers.  To try to use some sort of duplexer, you will spend a whole bunch of money and probably not be satisfied with the results you get.  

Hope this helps

If the two antennas can have a common feedpoint (like two dipoles strung from the same coax) you don't need anything... just feed them off the same "center insulator". If not, then a coax switch is the only way... well, you COULD build a duplexer for these bands, but it'd be HUGE! In other words, beyond reasonable specs...
