Buying Guide
- Carrier compatibility: Confirm that the booster supports your primary carriers (Verizon, AT&T, T-Mobile, etc.) and the specific bands your devices use.
- Band coverage: Look for Band 12/13/17 support for rural and highway coverage, or broader band sets if you travel across varied areas.
- Installation effort: Magnetic roof antennas enable easier, drilling-free setups, but verify vehicle suitability and mounting options.
- Multi-user capacity: If multiple people in the same vehicle need improved service, choose a model designed for concurrent use with several devices.
- Signal stability features: Automatic gain control and adaptive signaling can reduce dropouts; consider models with built-in ALC or similar technology.
- Environment and usage: For off-road or RV use, favor rugged builds and higher gain to overcome longer signal paths and tougher environments.
