For the heck of it, I swept a cavity leftover from a Decibel Products
DB-4076 pass/reject duplexer. It gives 32 dB rejection at 444.6 with the
pass tuned for 446.66 (about mid-way between your two freqs), insertion loss
about 0.7 dB. A bigger, higher-Q cavity would likely provide more
attenuation, but if you want this one, you can have it. It's not going to
win any beauty pagents as far as its cosmetic condition goes, but it
works...
For a power divider, since your Rx's are close in frequency, they'll provide
a decent match at both frequencies so you probably don't need any isolation
in the splitter. You can just use a pair of 75 ohm odd-quarterwave cables
as a power divider.
