Wrapping the outside of the cable with foil can create additional paths for current to flow on the outside of the foil. The foil shield and the braid need to be in contact with each other to achieve better shielding than using either foil or braid alone. However, a cable of foil and braid shield is not recommended for use in duplex systems such as a repeater or connections between the repeater and duplexer. A better cable would be a double braid shield such as RG214 or RG142.
