If a dedicated wire does not enter where AC electric also enters, then an item that actually does surge protection is missing or compromised.
Remember, destructive surges are electricity. That means it must have both an incomng path and a completely different outgoing path to earth. Typical incoming path is AC electric (ie due to lightning striking highest wires on poles far down the street). Outgoing path can be that dedicated satellite/cable line. Damage is often on an outgoing path. Naive consumers, only using speculation, assume a satellite/cable was the surge incomng path. Because damage was on the coax or HDMI port - the outgoing path.
Protection is never about a protector. Protection (from a type of surge being discussed here) is always about what harmlessly absorbs hundreds of thousands of joules. The critical term (and what shuold have everyone's attention) is single point earth ground (all four words have electrical significance).
'Dedicated wire' is mostly irrelevant to protecting electrical and electronic devices. Only useful recommendation comes with numbers. A protector is only as effective as its earth ground. Relevant numbers - where do hundreds of thousands of joules harmlessly dissipate?
