At the heart of all of our systems is an amplifier designed to improve coverage for wireless products within a facility.  Combined with interior ceiling mounted low profile antennas, and an exterior mounted Yagi or Panel Antenna, the amplifier boosts the signal level for distribution within the interior areas, reducing the problem of dropped calls and signal fades. The CA Building Repeater Packages can also be used  in mobile applications, improving voice quality and range in areas of poor cellular coverage.

We can improve any cellular providers service, including Nextel, Verizon, Alltel, Sprint, Cingular, T-Mobile, and Blackberry operating under any type of service including AMPS,TDMA, CDMA, GSM, iDen , GPRS, and 3G.

DA4000  Direct Connect Cell Phone Amplifier  38dB gain



Cell Phone Amplifier for Remote Areas


The DA4000  is a direct connect amplifier.  The boost from your signal with this product is coming directly from an outside antenna.  You can install the exterior antenna outside a home, car, building, or marine vessel.  With the DA4000, there is no interior antenna to install like DA4KMR-10u, DA4KMR-30u, & DA4KMR-50u.   The exterior antenna is connected directly to the amplifier.   Your cell phone is then connected directly to the amplifier.  This means that the DA4000 requires you stay within a small proximity of the amplifier.   For that reason, we suggest the DA4000 for remote areas.  We suggest the DA4000 for convertible cars since an interior antenna is not required. NOT FOR USE WITH NEXTEL CELL PHONES

DA4000MR-10a Wireless Cell Phone Amplifier (38dB gain)



Cell Phone Amplifier for Cars / Trucks


The DA4000MR-10a is a great wireless cell phone repeater for cars and trucks.  Unlike the DA4000, the DA4000MR-10a has both an interior and exterior antenna.  Since the DA4000MR-10a is best suited for cars, the exterior magnetic mount antenna provided in this package needs to be installed outside the metal roof of the automobile.   The interior antenna inside the car or truck needs to be installed 2’ from the exterior antenna.  Your cell phone will receive the increased signal from the interior antenna that acts as a signal repeater. Since the DA4000MR-10a requires an exterior antenna on the roof of an automobile, it is suggest that the DA4000 be used for convertible cars.  The DA4KMR-10a provides up to 500 square of wireless cellular connection to the cell phone amplifier while inside the vehicle. NOT FOR USE WITH NEXTEL CELL PHONES



DA4000MR-30u Wireless Cell Phone Amplifier (38dB gain)



Cell Phone Amplifier for Boats / RVs


The DA4000MR-30u is a perfect wireless cell phone signal amplifier for marine vessels, RVs, and small buildings.  This package includes an 18” fiberglass exterior antenna that needs to be installed 15’ to 20’ away from the interior antenna.   It is suggested that the interior antenna be located in a visible location and not behind an object or wall.  The DA4000MR-30u provides up to 1,000 square feet of wireless connection to the cellular amplifier while inside a boat, yacht, sailboat, RV, or small building.  Since marine vessels vary in size, we suggest you consult with one of our representatives before purchasing DA4000MR-30u for your boat.

DA4000SBR-50u Wireless Cell Phone Amplifier (60 dB Gain)



Cell Phone Amplifier for Home / Office


The DA4000SBR-50u is a superior wireless cell phone signal amplifier for homes, buildings, oversize RVs, and large marine vessels.    The package contains an exterior antenna to be installed on the roof of a home or office.  The interior antenna included with the DA4000SBR need to be installed at least 40’ from the exterior antenna.   The interior and exterior antennas must be separate by a wall to work properly.  A window does not equal a home or office wall, therefore does not provide the attenuation required for the cellular amplifier to work.  Once the exterior antenna, amplifier unit, and interior antenna is installed properly, the DA4000SBR can give you up to 5,000 square feet of wireless increased signal strength.
