With the test equipment essential for troubleshooting and three critical system modules, the Field Repair Kit includes everything needed to make effective and efficient “in the field” repairs to a SAC NDB System. The antenna simulator and test load allow each section of the system to be isolated ensuring proper functionality, therefore isolating the issue. If a module needs to be replaced, simply exchange it for the new module in the Field Repair Kit, and send the failed module to SAC for repairs. Having the test equipment and modules on hand can greatly reduce system downtime, and even reduce the need for a service call. Save time, money and undue stress; own a Field Repair Kit.
