I'm 99% sure that these splitters are either bad or you are accidentally
shorting the shielding when making the tests. The outer shield is that, a
shield which should be connected to ground. If there is continuity between
the lead and the shield, you would be shorting out the signal to ground.

It's only a short at DC, which is what your meter is measuring. These
devices are essentially transformers, and at RF, the inductance of the
windings provides the proper impedance matching. (Assuming all the
ports are properly terminated.)

In short, the OP's measurements are exactly what would be expected. At
DC, there should be continuity between all four terminals of a two way
splitter. (It, Out2, Out2, shield/case.) It looks something like this:

(------ Out 1
In ---) (
) (---+-- Shield
) |
) (------ Out 2
Shield -+-) ( |
| (---+-- Shield
\--Case-+

(Note, it may not be clear, but the shield side of each winding is
connected to the case, and as such, they are all tied together.)

To the OP: Do you have a specific problem with your equipment, or are
you just measuring for fun?
