This cartoon describes how MHD wave transport may contribute to footpoint heating. The left panel here is the relevant one, and nicely shows the observer's viewpoint as a radio dish, rather than an eyeball. This panel also shows trapped electrons in the closed loops. The right panel shows how this might fit into the CSHKP model.
