yes, but I'm still unclear about what center frequency I could use with
it. Thw spec sheet didn't clear it up. I'll have to try to call them back.

Brian,
Bandpass filters come in different band "widths". Some are full-band
filters that pass 902-928 MHz and some are single-channel filters
that are narrower and pass only one channel. The bandwidth of the
two Ubiquity filters are a little narrow to use across the entire
band but if you are using 912 or 917 as center frequencies, they
should work well. If you're using a lower center frequency, you'll
need a filter that has a bit wider bandwidth but which still
attenuates the paging frequencies a lot. The availability of good
whole-band bandpass filters seems to have deteriorated a bit in the
last year. There are more filters available but they seem to have
poorer characteristics and sometimes higher prices. I just looked at
RFLinx and Hyperlinktech and I am not happy with their current
offerings. I did discover a notch filter that is tuned to attenuate
the paging frequencies while passing the 902-928 frequencies. I
don't know the pricing but if it's priced reasonably then it looks
like your best bet. Here's the link:

It's the filter at the bottom of the page. If you call them to get a
spec sheet and to check pricing, please share that info.
Thanks,
