Moot.... Thats... never mind....
Bambam,
This maybe too late to help you with the race but...
Let me explain first that the sleeper companies, regardless who they are, are not RF engineers. In some cases they are not engineers at all but that is for another post. Many times they just go to a catalog and pick one that will conform to thier 'design' while other times they just rig something up with a Radio Shack FM antenna (what I have with my Bentz sleeper). Most of the time they do not properly test them in areas outside of the factory and think that everyone will have the same reception as they do sitting under the TV tower.
Second the antennas that are built in are not made to last, they break.
Third, and I should have opened with this, it depends on where you are sitting to get some of the channels. Sounds stupid but it happens.
My reception is marginal at best with my "Factory" builtin antenna, even sitting in Chicago. When I arived in RIchmond, I could not get Fox. After I had my truck washed and pulled into the same spot, I got Fox without any problems, crisp picture. This morning, nothing.
