So a loose ferrite bead is sufficient for this connection, whereas a
pi filtered connector was needed for the signal and control lines. Is
this because the remote end of the 1PPS coax terminates outside the
receiver room, whereas the former lines terminate inside the receiver
box?

How about the analog power-supply lines? Am I correct that these will
need pi filters, because the power supplies are shared with the
receiver?

Also, you mentioned in an email last week that there would be "a big
fat ground bus" between the receiver and CCB boxes. Are you thinking
of a thick cable (how thick?) bolted to the two cases?
