Please take note that Stub Poles need to be assessed in two separate steps right now with Quick Pole. Once you have analyzed the whole project, go back and put Point Loads on the stub poles at the same height and direction as the overhead guys. You can get the tension values to use from the Guy and Anchor Summary Report of the mainline poles immediately after the first main analysis.
There are plans in the works to eliminate this process for stub poles later this year. However this is the process that should be followed for now.
