Yes, that would be a BIG duplexer.  Many 10m repeaters go for multiple sites
instead of a duplexer.  As for UHF CB, well, the frequncy is nice to handle,
but the split is wicked.  I did read somewhere that the first time a cavity
manufacturer was given the specs, they were like "Are you kidding?".  The split
is only 750 kHz on a 477 MHz carrier frequency.  Much less than the typical ham
or commercial UHF repeater.

JA> To have had a repeater back in the day...

Would have been, umm, interesting.  I do enjoy 10m FM when the band opens.
