Product description

The Clear Voice Dual Band Kit is perhaps the best value for money for a simple, dual-band cell phone booster for in-building use. The kit includes a directional yagi antenna which results in superior coverage (as a result of a higher signal to noise ratio), and uses high-quality milled-aluminum casing for better isolation and amplifier performance

The kit is designed to amplify cell phone signals on both the Cellular (800/850MHz) and PCS (1900MHz) bands, and is optimized for easy installation, including everything you need to improve your voice and 2G cell phone reception.

If you want to improve 4G LTE signals in your home or office, take a look at our 4G LTE kits page. If you have a broadband connection and Wi-Fi at home or in your office, it's likely that you do not need a 4G LTE kit, as broadband connections will handle your data connection.

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 4,000 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
