Get more bars with the most powerful repeater system on the market. Digital Antenna’s PowerMax™ 4KSBR-50M 70dB gain wireless repeater system boosts the signal strength of your cell phones or air cards to 3 watts, greatly improves transmit and receive signals and can be used in a variety of locations. This translates into fewer dropped calls, clearer connections and stronger signals inside your e, yacht, or  sailboat r . In addition, Digital Antenna’s cell boosters extend the life of your cell phone’s battery. For use on all carriers except Nextel or iDEN. Not for use in open console boats.

DUAL BAND: FCC and IC approved for use with all North American cell phones operating on 850 or 1900 MHz (except Nextel or iDEN).

Application: Multiple rooms in home, office,  large yacht or sailboat (not for use in open console boats)
Range/Performance: Enhances multiple cell phones up to 60‘ from inside antenna*
Advantage: Wirelessly amplifies up to 20 cell phones in multiple rooms
Requirement: 25’ separation plus a structure between inside and outside antennas

* Enhanced distance from inside antenna varies based upon outside cell signal strength. A weaker outside signal results in a smaller distance from inside antenna. For a larger enhanced inside coverage area, use ultra low loss cable and/or add a directional outside antenna (for fixed locations only). To use a cell booster, a usable cell signal must be present at the location of the outside antenna.
