The zBoost YX030-0W8 8" Window Entry Cable allows you to pass the signal through a window frame. This item allows the cable to pass through a window or doorway without drilling holes. The connector ends are F(Female) to F(Female). You will need a second RG-6 cable with this accessory. One cable goes between the Base unit and this Window Entry Cable and the second cable would go between this Window Entry Cable and the Signal (Outdoor) Antenna.
