[mythtvnz] RG6 cable and mains power cable fed through same junction box - interference likely?

[Noel & Di]

DON'T do it.  RG6 is NOT insulated for installing with mains cables.  If 
your water-pipe conduit is large enough run your new cables through 
that.  Otherwise get digging !!
Imagine if the 230v cable has had it's sheath damaged by the drawing-in 
of the phone cable (I've seen this many times before) and the insulation 
is only just intact.  Now it would be scary to think of the consequences 
of livening up the braid of you RG6.
PLEASE DON'T GO THERE
