As others mentioned, vertical antenna separation is most of the key. I
have successfully installed in-band remote bases at most of my 2 meter
repeater sites, and where you cannot get a bunch of antenna separation,
filtering is a necessity. Most of the time, a notch filter placed in
the remote base line tuned to the receiver frequency can really help.
It does the same thing as your duplexer, notches transmitter side band
noise on the repeater receivers frequency.
