Use the same procedure for installing the adjustable stays. Hollow or Cinder Block wall Mount Bracket The procedure for mounting a ViaSat antenna on a hollow or cinder block wall is very similar to mounting on a brick (masonry) wall. The primary difference is the mounting hardware. Important considerations: Use hollow wall toggle anchors with a strength of at least 300 pounds of pullout pressure. To allow for mounting the stays, the mount anchors must be installed at least 28 inches from: o The edge of a door o The edge of a window o The edge of building corner o The top of the wall Position the mount to allow for properly mounted stays on either side of the bracket. Block walls covered with stucco are not an approved surface Mounting Materials for Mount Bracket The Technician must provide the following materials: 6 ¼-inch hollow wall toggle anchors 4 #20, ¼-inch X 3-inch machine screws 4 5/16-inch washers Installing the Mount Bracket into Cinder Block 1. To begin installing a wall mount on a hollow or cinder block wall, locate a block that is at least 28 from the edge of a door or window, the corner of the building or the top of the wall.
