Conductor Material: Ensure it is 100% Pure Bare Copper rather than cheaper Copper Clad Aluminum (CCA), as pure copper maintains signal integrity over long exterior runs.
Jacket Type: Look for LLDPE or High-Density Polyethylene (HDPE) to protect the internal copper from water ingress, severe cold
Shielding (Optional): Opt for FTP/STP (Shielded) if routing the wire alongside power cables or outdoor security cameras, or UTP (Unshielded)
