Digital Antenna's DA4000 PowerMax 3 Watt Dual Band Cellular Amplifier improves communication by bringing maximum power to all bands of your cell phone. This bi-directional amplifier features Dynamic Variable Gain Control to regulate the amplifier's output to any cell carrier's 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 DA4000 with any of our cellular antennas (required, not included) and increase the gain of your cellular phone up to 30dB.

Patent Pending Technology

Digital Antenna's amplifiers feature Dynamic Variable Gain Control to regulate the amplifier's output to any cell carrier's tower whether the user is directly under the tower or miles away.

Features:

• Increases cell coverage up to 50+ miles
• The best solution in areas of extremely low outside cellular signal
• Improves call reception
• Greatly enhances data and cellular internet connection
• Extends the life of your cell phone battery by using less battery power
• Supports multiple cell phone carriers and technologies (all US carriers and technologies exept iDEN: Nextel, SouthernLINC)

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.

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.

Package Contents

• Includes DA4000 bi-directional dual-band inline amplifier
• 12VDC cigarette style power cable
• 3' 9" cable to connect from amplifier to cell phone adapter cable (not included)
• Requires (not included):
  • Cell phone antenna
  • Cell phone adapter cable
  • NOTE: Due to the higher SWR of glass mount antennas (for example, the 301102 or 301114) they should not be used with this amplifier. Recommended antennas include magnetic mount, permanent mount (NMO), Yagi antennas and all Digital Antenna antennas.

In order to connect a Wilson Cellular antenna and adapter to the DA4000, an FME/M to Mini UHF/M and FME/F to Mini UHF/F adapter are required. We include these parts with purchase of this DA4000 inline amplifier.

FCC & IC approved to amplify all North American cell carriers operating on 800/850 and 1900MHz. Not compatible with iDEN (Nextel, SouthernLINC, Mike.)
