For 120VAC, I know that 'splices' in NM/Romex are not allowed behind drywall: there must be a junction box to inspect the splice.
For low-voltage, such as CATV, how big of a deal is it?
The previous owner left my house with a CATV splice (pictured below), and we're about to add drywall to this ceiling.
Do I need to remove this CATV (RG6 Quad Shield) cable and re-run it as a continuous run with NO splice? (Or add a junction box for access; but I don't want to do this).

Low-voltage stuff isn't regulated in that way. Just know that you lose signal quality with a splicer like that, so some means of eliminating it later is a good idea.
