The MR PowerMAX Tri-Band kit is designed for universal mobile coverage on the go. The MR PowerMAX Tri-Band enhances signal strength to your mobile phone or broadband 3G dongle by capturing the weak signal through an external aeiral antenna that provides input to a Tri-Band amplifier compatible with all GSM Voice and all data networks. This unit the lowes cost solution that provides coverage on all three of these bands simultaneously. This low cost solution will provide a reliable phone signal for areas up to 1000 square meters depending on the antenna input signal.

Installation of the PowerMAX Tri-Band repeater is simple and takes minutes. Just mount the external yagi aerial  and connect to the repeater input port. At the output of the repeater connect the indoor coverage antenna then connect the power. For best performance the external aerial should be mounted in the location with the strongest signal strength. The effective coverage area of the unit depends on the input signal provided from this antenna. The PowerMAX Tri-Band comes complete with:

•     Tri-Band Repeater Amplifier
•     External Tri-Band High Gain Yagi aerial
•     Indoor high gain tri-band panel antenna
•     10 m coax to connect to repeater
•     AC/DC power supply
•     Easy to follow installation manual
