Description
The quad shielding in this RG6 TV cable refers to the four layers of shielding that are designed to reduce interference and signal loss. The layers include a foil layer, two layers of braided shielding, and an outer jacket. The foil layer helps to prevent electromagnetic interference (EMI) and radio frequency interference (RFI) from entering or exiting the cable. The braided shielding layers provide additional protection against interference, and the outer jacket provides physical protection for the cable.
