Plug into your TV, Scan for channels, watch TV Multi-directional element and double-sided Black or white design: no aiming necessary and comes with 12ft of high performance coaxial cable Indoor installations can be problematic for two reasons. First, the antenna will be lower than a roof-mounted installation, often limiting line-of-sight. Second, the digital signal is weakened by every wall the signal must pass through. This is why we recommend placing your indoor antenna as close to a window as possible (again, the higher, the better).
