Digital Repeaters

DSP85 Original Series

The DSP85 utilizes Digital Signal Processing (DSP) technology to achieve the highest level of performance and flexibility available today. This product offers major benefits over traditional repeaters including unlimited spectrum agility, sharp filtering, and state of the art monitoring and control.

DSP85 & DSP95 Modular Series

1/2 Watt and 1 Watt Single, Dual, Tri and Quad Band Repeaters

 

CSI Modular 250 and 251 series addresses the need for integrated tri band configurations. Its modular form factor permits growth from a single band up to 4 bands in a single integrated package that can be wall or rack mounted. The modular style digital repeater series is the industry’s most flexible repeater. The versatile, lightweight design offers many options including multiple frequencies, custom pass band filters, output power options, rack or wall-mount capabilities, and numerous port configurations – providing a user-friendly, easy-to-install repeater solution.

 

5 Watt Single and Dual Band Repeaters

 

CSI 255 series has the same integrated tri band configuration as the 250 series at a higher power options. These units are modular, in-building digital repeater that allows for the direct feeding of larger coax DAS systems. Areas as large as 150,000 square feet can be covered without additional hardware and installation costs or the complexity of a separate DAS system.

DSP85 Digital Repeater

DSP (Digital Signal Processing) technology is utilized to achieve the highest level of performance and spectrum agility. DSP filtering provides unmatched selectivity and can be finely tuned to help overcome difficult RF problems such as adjacent channel interference. The CSI Digital Repeater permits re-tuning of multiple pass band configurations, locally or remotely, with virtually no downtime. The Graphical User Interface allows for effortless set up and monitoring via a standard web browser.
