What to do if SureCall Extender indoor signal coverage has not improved after installation?
- NnweberAug 8, 2025
If indoor signal coverage hasn't improved after installing your SureCall Extender, check the outdoor antenna installation, ensuring the mounting area is free from obstructions. Also, verify the outdoor signal strength at the antenna's location and confirm the antenna is correctly aimed towards your carrier's closest cell tower. Finally, ensure all cable connections are tightly fitted to the booster and antennas. Remember that signal bars are not always reliable, so test the signal by making a call.
