Have you ever asked yourself how to choose a good 4g signal booster out of so many options existing? We can offer you several options so you can have some ideas concerning what to choose. You can still contact us for help!

How to direct the antenna

The inside antenna is omnidirectional, so it doesn’t really matter where you direct it. But did you know that the outside antenna works best when it’s directed towards the nearest cell tower? It increases the signal even more.
