The problem we are now having is we keep losing the signal from the TV station & we get a blank screen, reading "low HD signal"...thought maybe the trouble was the wrong antenna..we have the crank up antenna that came on the roof from the factory.

That sentence makes it MUCH clearer. What is currently on the roof? If you cannot find anything on the antenna, a picture will do wonders. Its probably not the "wrong" antenna, but maybe not the "right" antenna for what YOU do.
