...have to recalibrate my dish? I recently changed rooms and needed a to extend the coax cable to reach into another room. I extended it by connecting the end to a splitter attached to another cable to make it longer. I lost signal to some channels due to the splitter. My plan now is to replace that with a single 50 ft. cable to increase signal strength, but would i have to recalibrate my dish once I unscrew the LNB to replace the cable ?
