The face plate on the mount will accommodate the remote head bracket that comes with the TYT TH-7800 and TH-9800. The face plate on the LM-101 has a 4 hole AMPS pattern, two of the holes will line up with the holes in the TYT remote head bracket, just run the included nuts and bolts through the holes and tighten. The base can be drilled into solid, flat surfaces, such as walls, tables, and workbenches. The AMPS pattern consists of four holes located in a rectangular pattern spaced at 30.17mm x 38.05mm (measured as the center-to-center distance between holes). This tough mount is also ideal for mobile radio holders, housings, and other devices used by public safety, construction, and utility applications. This package includes only the Heavy-Duty 4-Hole AMPS Mount with 4-Hole AMPS Head. This tough, low-vibration mount measures 5.25 inches high from end to end and is made of a combination of nylon and fiber. The arm of the mount swivels on both the top and the bottom, providing 360-degree rotation and the ultimate flexibility in positioning the device at any angle.
