Cell signal boosters · Est. 2002
Stop dropping calls.
Start extending signal.
Wi-Ex — Wireless Extenders — makes the zBoost line: signal boosters that grab the faint outdoor signal your phone can't hold and fill your home, office or vehicle with bars. No internet needed. No subscription. Just coverage.
How it works
Three pieces, sixty minutes
Find the signal
An outdoor antenna catches the faint tower signal your phone can barely see.
Amplify it
The booster inside amplifies that signal up to 20× and rebroadcasts it.
Fill the dead zone
Calls, texts and data work everywhere the boosted signal reaches — thousands of sq ft.
Who needs a booster
Built for the dead zones
Basements & interiors
Concrete and metal eat signal. A booster brings the outside bars in where walls fail.
Rural & edge-of-tower
When the nearest tower is a rumor, a directional antenna plus booster turns one bar into five.
Vehicles & road trips
The Mobile Go keeps calls alive through the dead highways between towers.
Your next call shouldn't depend on where you're standing.
