Product description

The SmoothTalker Z1 60 dB Signal Booster kit increases 2G/3G and Sprint 4G LTE voice and data reception. The amplifier unit can be used with optional splitters and antennas to provide a very large coverage footprint up to 3,000 sq. ft. The booster incorporates dynamic adaptive gain control for powerful performance and clear reception.

The Stealth Z1 range is best suited to urban or suburban areas and areas where existing outside signal is strong. If existing outside signal is weak, you may wish to use the Smooth Talker X2 range.

The Z1 60 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.

This kit includes inside and outside antennas, amplifier, and power supply. The unit comes with sturdy long lasting cast aluminum housing.

Outside Antenna

The outside antenna is a wide-band omnidirectional antenna. Omnidirectional antennas receive and send signals in a 360º radius. They can receive signals from multiple cell towers and are best for boosting signal on many different carriers. They are excellent in most situations where the existing outside signal strength is moderate to strong. If the outside signal is weaker than that, you may need the Stealth Z1 75dB which comes with a directional yagi antenna instead. The antenna has 18’ of cable attached. The antenna comes with mounting equipment including stainless steel screws and double sided tape to mount to poles, walls or windows.

Inside antenna

The inside antenna is a wide-band omni directional antenna for use with the amplifier unit. The “blade” style antenna is mounted directly to the inside antenna connector of the booster. Omni-directional antennas broadcast and receive signals from all sides. They are designed for central locations with 360º coverage.


The MCT-Female amplifier unit comes with MCT-Female connectors and 200 series cable for maximum performance. The cable lengths included are 18FT (attached to outside antenna) + 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 3,000 sq. ft. coverage
Medium outdoor signal (3-4 bars) up to 2,000 sq. ft. coverage
Weak outdoor signal (1-2 bars) up to 1,000 sq. ft. coverage
