How it Works

Plus Cell Phone Signal Booster

The booster communicates incoming and outgoing signal to cellular devices and towers. The 4K Plus has a maximum signal gain of 65 decibels and power output of 10 dBi to improve signal strength.

This wide-band booster can improve signal strengths on any device. It is compatible with any carrier network such as AT&T, T-Mobile, Verizon, Sprint and US Cellular.

High-Gain Outdoor Directional Antenna
The outdoor antenna helps the booster communicate with distant cell phone towers. This signal booster kit includes a powerful 9 dBi directional outdoor antenna receives signal.
Users can mount the antenna on a mast using the mounting hardware in the kit. Masts can installed on roofs, balconies or from the ground. (Please note, antenna masts are not included in this kit)
Built-In Indoor Panel Antenna
The indoor antenna distributes and sends signal to/from the booster. The Plus unit is integrated with a 7 dBi indoor panel antenna. Since the panel is built into the unit, user can simplify installations with less cable runs.
Expanded Coverage with a Secondary Indoor Antenna

The Plus unit can distribute signal between a maximum of two different indoor antenna. Add on a HiBoost Indoor Antenna Kit to expand the Plus signal booster’s coverage area. Simply plug in the antenna to the port on the booster and you are ready to boost signal from two different antennas.

This cell phone signal booster has a internal antenna that distributes cellular signal.

It also has additional indoor antenna ports that allow users to split cellular signal between two different indoor antennas.

Customize a cell phone signal booster set-up and expand signal coverage area directly from the booster unit.
