First off, Omni directional anntenaes work equally poorly in all directions. In our previous trailer I replaced the Jensen Omni directional with a King Jack that rotated. Our reception in the driveway improved from a couple stations to about 12. Common online wisdom is the wingard is a better unit, but you have to have clearance on the roof for it to fold down flat. The King Jack has roughly the same profile as the omni directional. The reason manufacturers are going to omni directional is they don't have to have a spot for the rotation handle inside the trailer. I had to cut out a blank panel in the cabinets to access the handle.
