Where in-vehicle mobile signal drops out

A vehicle body or enclosed cabin weakens the mobile signal reaching the people inside. Calls break up and delivery updates wait, even where reception outside is usable.

Vehicles and vans

Keep phones and cellular work devices connected inside the cab.

Boats and yachts

Bring available coastal mobile signals into enclosed on-board spaces.

Fleet installation

Choose antenna mounting and power arrangements around each vehicle type.

How the CEL-FI ROAM R41 boosts signal on the move

We supply the CEL-FI ROAM R41 mobile repeater with its antenna kit and help you choose the installation for your vehicle or craft. The external antenna receives the available mobile signal and the internal antenna brings it closer to the phone or cellular device.
