PowerMax™ Marine & RV Cellular Booster
50dB Gain 3 Watt Dual Band Wireless Repeater System

Get more bars with Digital Antenna?s PowerMax 4KMR-30M wireless cell booster. This 50dB gain wireless cellular repeater system boosts the signal strength of your cell phones or air cards to 3 watts, 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 home, office, cabin boat or RV. 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.

Application:One to two rooms in home, office, RV or boat with cabin (not for use in open console boats)
Range/Performance:Enhances multiple cell phones up to 25' from inside antenna *
Advantage:Wirelessly amplifies up to 20 cell phones in one to two rooms
Requirement:12' 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.
