That bi-horn antenna looks like a load of bull to me.
My tv stick is several years old. It was only a few dollars on ebay. But it's done the job quite well. Sometimes the little antenna sitting by the window is all that's needed, at other times I've hooked it to my 4 bay antenna. I've pretty much stopped taking my small kitchen tv from home with me.
New ones have a lot more features although even this one can act as a PVR.
