Here's a schematic:

Sorry, but I can't make much sense out of the drawing. The
resistors (where are the other ends??) and the "no connects"
are a big mystery from this end.

Any clue as to Coax 1 / Coax 2, which is the input feed and
which is the outgoing feed? If so...

You need is a simple "Directional Coupler". Probably a 14dB
version. A DC is an unbalanced 2-way splitter. Instead of
both splits being -3.5 dB down like a conventional 2-way,
one leg is very low loss ( typically 1dB) and the other is
high loss (-14, -16, -22dB etc.)

It has 3 female coax ports: IN / OUT / TAP. The distribution
cables (the 2 on the back of your current gizmo) go to the IN
and OUT, there is very little loss between them, the idea being
to pass along as much signal as possible to the next guy.

The TAP port is the "high loss" leg which will poke out through
your new wall plate, having a single hole in the middle for your
coax connection. You secure it to the plastic plate with a hex
nut.
