Thanks again to our resident RF maven VOS for this great little tool! If you are worried about signal loss between points in your system, this excel spreadsheet will help you figure out where you might be running into problems.
Simply feed in the distances into the top row, measured in feet, between your cinema connection kit and your splitter, then feed in the cable lengths between each splitter and the receiver. If any number on the bottom is greater than 45, you will surely have signal loss problems. Of course there can be other factors such as loose connections or unknown cabling issues, so use this as a starting guide, and give yourself some leeway when planning cable runs.
