CommScope's SpanMaster software is a tool designed for use in the calculation of sag and tension of single or multiple cable combinations under various environmental loading conditions. SpanMaster software takes the user through a logical step-by-step process of information entry and produces sag and tension results for any cable span.

SpanMaster is a great tool for determining the "what ifs" of aerial plant design. SpanMaster makes it easy to conduct a design "checkup" before actual installation begins to determine how strand size, cable bundle size, span length, and the amount of sag will affect the tension being applied to the span's poles under loaded conditions. With SpanMaster the user can easily change design variables one at a time and watch as the resultant span tension changes in response. Finally, the printed documentation provided by SpanMaster can be a very important tool when using jointly shared poles. 

Download Patch: After you download SpanMaster and try to open it, you may receive an error message stating that your computer is missing MSVBVMSD.DLL. Msvbvm50.exe is a self-extracting file that installs the latest versions of the Microsoft Visual Basic run-time files that all applications created with Visual Basic 5.0 need in order to work. If this happens, go to MicroSoft site and download the patch.
