Hi everyone,
I am currently planning to run an ethernet cable to the upstairs of the house, however, the walls have corrugated ducts to run the cables through, I would like your opinion on whether it is necessary to run a shielded cable through this duct or it can be unshielded.
NOTE: These ducts do not carry electrical wires.
Thanks for your reply, this ducts are flexible corrugated ducts and they are for passing cables through walls, these are not for air conditioning but I am not clear if they are located or pass near the ducts of electricity cables.
