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 wireless broadband 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 home, office, yacht, sailboat or
RV. In addition, Digital Antenna’s cell boosters extend the life
of your cell phone’s battery. Not for use in open console boats.
DUAL BAND: Operates on 850 or 1900 MHz frequency bands (except

||Multiple rooms in home, office,
RV, large yacht or sailboat (not for use in open
||Enhances multiple cell phones up
to 60‘ from inside antenna*
||Wirelessly amplifies up to 20 cell
phones in multiple rooms
||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.
HOME: Enhanced signal penetrates up to two interior walls with 70dB
BOAT: Internal antenna must be used inside. Enhances signals inside
the cabin only.
RV: Directional inside antenna must
face forward, away from external antenna.
