The antenna can also be attached vertically to an external or internal wall if that is moreconvenient than placing it on a horizontal surface.
1.Holding your antenna up, find a wall location that ensures a strong signal. It is recommended that you use an extension cord to temporarily locate your Xpress XM antenna outdoors while optimizing the antenna location with the “Antenna Aiming” screen.
2.Attach four screws to the wall using the template provided. Use screws with head sizes small enough to fit in the center of each of the four holes but large enough not to pop out of the elongated sections. Leave 1/8 inch of the screw shanks behind the heads sticking out of the wall.
3.Tilt the antenna fully back on the base, place the antenna base on the four screw heads with the antenna pivot at the top, and pull down approximately 1/4 inch until the base is firmly secured. Note that the XM logo will be upside down when the antenna is properly installed.
4.Tilt the antenna away from the wall/base until the signal strength is optimized.
