iHeart is still streaming. I used to have luck by running solid core wire to the window surreptitiously and connecting it to a metal pipe there. I am not sure how your cube farm is set up.
I’m exploring the feasibility of doing the same thing. Have to negotiate three modular cubes, but do have an uninterrupted set of panels to the window. Can’t go over, have to go along the floor. All depends on whether or not I can get the wire under each panel.
