Description Brand New for Many HAM Radio Heads, Satellite Radio Cradles and Video CamerasCar Cup Holder Mount with AMPS Adapter Description: Look mom, No Glue! This mount attaches to devices with 4 screw holes using the AMPS pattern. The AMPS pattern consists of four holes in a rectangular pattern spaced 1.188 inches by 1.813 inches. Some manufacturers also have 2-hole adapters that support the diagonal measurement of 1.912 inches. This mounting design pattern is fairly well-known in the HAM Radio industry where many head plates use that 4-hole pattern. We find that HAM Radio enthusiasts are pretty handy people and where the AMPS pattern doesn’t exist, they don’t mind drilling some holes to match up. The mounting base features an expandable base to fit most cup holders. A flexible gooseneck is included to help get the perfect angle. Swivels into landscape or portrait mode.
