Get more bars inside your home, office, yacht, sailboat or RV with the most powerful cellular signal 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. This greatly improves transmit/receive signals in a variety of locations, resulting in fewer dropped calls, clearer connections and stronger signals. 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, RV, 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. Installation examples:  |  |  | | HOME: Enhanced signal penetrates up to two interior walls with 70dB gain system. | BOAT: Internal antenna must be used inside. Enhances signals inside the cabin only. | RV: Directional inside antenna must face forward, away from external antenna. | See the data sheet for larger images.
