All of our vehicle cell phone signal boosters are 5G ready and will boost 5G signals across the 700 MHz to 2100 MHz frequency range.

There are five main variables that determine a booster’s performance:

1. Quality of outside signal
2. Maximum gain of the signal booster
3. Uplink and downlink power of the signal booster
4. Maximum gain of attached antennas
5. Quality of cables used in setup

Choosing the right vehicle signal booster depends on your vehicle type, the number of devices you need to boost, and your budget. We recommend buying the most powerful booster possible within your vehicle category, as you will find it provides the most consistent signal no matter where you go.

However, if you only need to boost one device at a time, there are boosters for that as well.
