I ordered one too. 2 comments: I had kworld stuff before, they are a little bit below ok, not horrible, but got what you paid for. At least, one can find them if stuff dont work. Second: they are notorius in give out rebate. Anyhow, only the HDTV antannae itself is ~$20.

Another thought about the winshield holder, the cup, sometimes, may loss suction and your lovely tablet may, MAY, fall from the winshield. I always put it in such a way, that the tablet will rest on the dashboard. Beware, as the tablet falls from winshield to the floor may kill the tablet.
