3 Watt 60dB Gain Dual Band Wireless Cellular Amplifier / Repeater
For use in large yachts, RVs 40' length or greater, homes and offices
You can now speak and be heard clearly on a cell phone inside marine vessels, RVs, homes and offices without feeling tied down. Digital Antennas PowerMax DA4000SBR increases signal strength and improves cellular communication without a physical connection to cell phone. This amplifier/repeater also boosts the performance and range of your cell phone up to 50 miles.
Stay Connected ... Wirelessly!
The DA4000SBR requires no physical connection to your phone. How does this work? An outside antenna receives the signal from the cell tower, the signal is amplified by the DA4000SBR unit and repeated to your cell phone through the inside antenna. No physical connection to your phone means you now have the freedom to walk around while talking on your phone. This technology even allows clean and clear wireless functioning of multiple cell phones operating on 800 and 1900MHz bands simultaneously, with a coverage area up to 5,000 square feet.¹
¹Coverage area is based upon an outside signal strength of -70dB. As outside signal strength decreases, coverage area decreases. For poor outside signal areas or for increased interior coverage, use a yagi (directional) antenna.
Complete Systems are Easy to Install
The DA4000SBR is sold as a complete system with everything you need for no hassle installation on your yacht, or inside your RV, home or office. This innovative design offers patent pending Dynamic Variable Gain control and amplification of transmit and receive signals. A minimum separation of 40 is required between the inside and outside antennas*. The DA4000SBR is the only FCC approved amplifier/repeater for use with all cell carriers in the USA and Canada.
DA4000SBR can be used with all 800 and 1900 MHz digital cell phones and tri-mode phones operating on CDMA, TDMA, PCS, GSM850/1900, GPRS and AMPS.
DA4KSBR-50U - For Large Yachts and RVs, Home, Office
²Requires a minimum separation distance of 40' or more, and wall/roof/bulkhead structures between inside and outside antennas (see model DA4000MR which requires less antenna separation).
The DA4KSBR-50U system is not for use in cars, open console boats, RVs less than 40' length or in open air without a roof/wall structure. For answers on installation questions, visit our Product Frequently Asked Questions page.
Optional: May also be used with Digital Antenna's 500, 800 or 900 Series 9dB gain premium quality cellular antenna line (antenna separation requirements must always be met).
To mount the amplifier/repeater's outside antenna on a standard 1"x14 marine mount, use model F114 1"x14 double female ferrule.

Comments about Digital Antenna PowerMax DA4000SBR, 3 Watt 60dB Gain Dual Band WIreless Cellular Amplifier / Repeater:
We are a police department and our facility is a metal building. Our cell phones could hardly get out and hardly receive calls. So, now we can operate our cell phones in a normal manner. Before, we had to go outside the building to get a good signal. The only regret I have is that I did not see your advertisement sooner.
