One of the cable TV signals might interfere with vital communications,
such as with fire, police or aircraft communications or navigation.

Now that you KNOW that you may be radiating signals that could interfere
with communications, you have an obligation to cease.

Deliberate interference with radio communications is a crime.



Interference in such a scenario is *extremely* unlikely. The power level is
low, and a small unshielded section is a horrible antenna. On top of that,
this would not be "deliberate interference". Putting a connector on there is
a good idea, it's the only right way to do it, but there's no need for
paranoia, there's nothing you could reasonably do that will cause any
undesired interference to anything else.
