This is an easy one. Figure 3.0 db loss, using a standard CATV splitter.

That's 3db inherent loss due to splitting. (Each signal is half the
original signal, or -3db.) With most TV splitters, add anywhere from
6db to 20db additional loss in the components in the splitter.

And ALL output ports must be terminated. If you move the scanner from
one cable to the other you'll get additional loss due to the
unterminated cable. (If there are more ports than scanners, you have
to connect a terminating resistor to each unused port.)
