Rats.  Is the antenna known to be good?  Is the Z12 providing bias on the
antenna cable?  Did the Z12 stop tracking right in the middle of the
session with no nearby events or configuration changes?  If you can
manually inject DC to the antenna with a bias tee, verify the presence of
signal with another receiver, then feed the signal to the Z12 (or use a
splitter to feed both receivers), that might be worth trying.
