Our latest additon to our ever growing line of repeater systems for home, small office, RV's and boats. The CM2KSBR system increases signal strength and improves cellular communication without a physical connection to cell phone.


• Wireless – no connections to cell phone

• Amplifies 800/850 and 1900 MHz bands (except Nextel) Voice and Data

(Verizon, ATT, Cingular, Sprint, Alltel, T-Mobile, Cellular One, Etc.)

• Use multiple cell phones and carriers at the same time

• Reduces dropped calls

• Up to 4,500 sq. ft. coverage area*

• Extends the life of your cell phone battery

• Approved and recommended by ALL carriers in the US and most in Canada!

Stay Connected ... Wirelessly!

The CM2KSBR requires no physical connection to your phone. How does this work? An outside antenna receives the signal from the cell tower, the signal is amplified by the CM2000 unit and repeated to your cell phone through the inside antenna. No physical connection to your phone means you now have the freedom to walk around while talking on your phone. This technology even allows clean and clear wireless functioning of multiple cell phones operating on 800 and 1900MHz bands simultaneously, with a coverage area up to 4,500 square feet.* . Larger System Here

* Coverage area is based upon a minimum outside signal strength of 65% or better. As outside signal strength decreases, coverage area decreases.

Complete Systems are Easy to Install

The CM2KSBR is sold as a complete system with everything you need for no hassle installation. This innovative design offers Dynamic Variable Gain control and amplification of transmit and receive signals. A minimum separation of 40’ is required between the inside and outside antennas unless isolating material such as metal roof/structure is placed between antennas.

CM2KSBR can be used with all 800 and 1900 MHz digital cell phones and tri-mode phones operating on CDMA, TDMA, 3G, PCS, GSM850/1900, GPRS and AMPS (does NOT cover Nextel - For Nextel Systems go here)
