Troubleshooting & Checking Your Signal.


Mount the antenna in the vertical position in an elevated and unobstructed place such as roof or high outside wall, away from other antennas, glass windows, and metal objects. Antenna should be as high and unobstructed as possible. Locating your nearby cellular tower used by your carrier and moving/directing your antenna towards it is very important for optimal installation of any outdoor antennas in a line-of-sight with the tower. Follow antenna-specific installations instructions for details.
