This bi-directional amplifier features Dynamic Variable Gain Control to regulate the amplifiers output to any cell carriers tower. This patent pending technology allows clean and clear functioning of the cell phone, whether under the tower or 30 miles away without power overloading or saturation. Combine the PowerMax DA4000 with any of Digital Antennas cellular antenna product line and increase the gain of your cellular phone up to 30dB.

Stay Connected
A superior signal reach booster, the DA4000 provides excellent amplification of transmit and receive signals while greatly enhancing range and system access, adding up to 30 50 miles or more of extended coverage. This translates into fewer dropped calls, clearer connections and stronger signals.

The DA4000 can be used with digital cellular phones that operate using CDMA, TDMA, PCS, GSM 850, GSM 1900 and AMPS. Can be used with tri-mode phones. Meets IS 95, IS 98, IS 2000 and IS 136 network standards. DA4000 is the only model approved for pi/4QPSK standard. It cannot be used with Nextel or iDEN.

For Land and Sea
Easy installation for boat, vehicle, RV, home or office. Connects to most existing hands free kits and hand-held cellular phones. The DA4000 offers superior performance and outstanding range, unequaled in the industry. The latest technological innovations designed, engineered and manufactured by Digital Antennas in the USA.

The DA4000 is the only amplifier FCC approved to amplify all cell carriers in the US.
