Frequently Asked Questions
How Does the Booster/Repeater Work?
- Outdoor antenna captures weak signal from nearest base station
- Signal travels via coaxial cable to the repeater unit
- Repeater amplifies the low signal
- Enhanced signal transmits to indoor antenna
- Indoor antenna delivers improved signal to mobile devices
Why is Signal Strength Weak at Coverage Edges?
- Verify outdoor signal quality and antenna orientation
- Check booster gain settings and connector tightness
- Adjust antenna placement or add additional indoor antennas
Why Are Signals Unstable After Installation?
- Ensure proper distance between donor and server antennas
- Confirm stable signal input from outdoor antenna
- Recheck system connections and cable routing
