The Quiver Navigator app is a productivity tool designed to help the cable television line technician more quickly locate impairments. This app is intended to be used as an optional companion tool with the Arcom Digital Quiver. The app stores electronic maps of each node, and displays all coax network components and street maps. The app alloys you to automatically identify and display the network connection point (hub, node, and device) based on current GPS location. After establishing the connection point, it will flag candidate impairment locations based on time distance to the impairment as measured with Quiver – for both CPD radar and NTC TDR modes. This provides a more intuitive representation as to the location of the impairment source, allowing for faster time in getting to the problem and performing the repair.
