Remembering that VF varies with frequency, it's best to tune the stub by measuring at the harmonic frequency(ies) it is intended to suppress. And while the tutorial you posted is a start, the ones discussing PLACEMENT of stubs along the line are more important when you get around to adding them to your station!
