Product description

The SmoothTalker X2 65 dB Signal Booster kit is a powerful in-building repeater kit. It increases 2G/3G and Sprint 4G LTE voice and data reception. The amplifier unit can power up to 2 Indoor Antennas and offers coverage of up to 7,000 sq. ft.  The amplifier is equipped with dynamic adaptive gain control to allow maximum performance for clear reception.

The sensitive repeater picks up signal as low as -117dB. It is ideal for isolated areas where existing outside signal is poor. If existing outside signal is strong, you may wish to use the Smooth Talker Z1 range.

The X2 65 dB amplifier has LED level indicators to make installation quick, easy and effective. The LED console also has a manual control override. Signal gain is improved with automatic oscillation control, and network overload protection, so that you have maximum gain and coverage.

Kit includes outdoor and indoor antennas, amplifier, and power supply. The unit comes with sturdy long lasting cast aluminum housing.


The included antennas are wide band directional panel antennas suitable for both indoor and outdoor use. A directional antenna is stronger than an omnidirectional antenna and so can pick up outside signal from further away. Indoors, the panel antenna can be fixed to the wall to allow optimum reception to targeted areas. Each antenna has 18’ of cable attached. The antennas come with an adjustable mounting bracket made of weather proof impact resistant plastic. It includes stainless steel screws and double sided tape to mount to walls or windows.


The N-Female amplifier unit comes with N-Female connectors and CB205 quad shield cable for maximum performance. The cable lengths included are 18FT / 18FT + 30FT.

How it works

how a cell phone booster works
1 - Outdoor antenna

The outdoor antenna receives and transmits signal to nearby cellphone towers. Outdoor antennas can be either directional or omni-directional.

2 - Cellular amplifier

The amplifier (or "repeater") boosts the signal coming to and from and going to the cell phone tower. The "gain" of the amplifier describes how strong the amplification is - you'll see that word scattered across our product pages.

3 - Indoor antenna

The indoor antenna rebroadcasts the signal inside the building. Some kits have more than one indoor antenna to help distribute the signal.


The coverage area you can expect from any signal booster kit depends on the signal strength outside the building.

Outdoor Signal Estimated coverage area
Strong outdoor signal (5 bars) up to 7,000 sq. ft. coverage
Medium outdoor signal (3-4 bars) up to 6,000 sq. ft. coverage
Weak outdoor signal (1-2 bars) up to 3,500 sq. ft. coverage
