Just a brief pitch on the commercial version. I had the idea of a pvc or hard plastic model that would be expandable whereas, it could be pulled out to fit snug in between any window sill application. It would also come in many colors, ie: red for brick builing, where it would be unseen. As there are many hams in apartment buildings with no balcony or cannot have a antenna, vertical type sticking out of the window, this seems like a great soloution. Guess I will wait and see.
