Back in the mid 80s, Costco was selling a 12 foot Janeil mesh antenna from their Anchorage store, and many were fooled by the low price. One of my dealer colleagues in Homer (as far as you can drive directly from the U.S. highway system), reported a problem with a subcontractor's weekend install. It was tested for tracking from 139 West down to about 91 West (elevations 21 to 5), and then left back on the westernmost satellite (139) when the installer left. When the owner called up a satellite to the east, the H to H mount came crashing down in that direction. The H to H mount had plastic teeth, and they had sheared off. Hope this is not one of those!
