Our Home 4G unit has a panel antenna included in the kit that is used as the outside antenna. The way to mount the antenna outside your home is to remove the back plastic panel on the antenna that reveals the mounting area. Please do not drill your own! If you take a flat-head screwdriver -while this is unplugged from the booster- you can pry up the piece of plastic which will then show the holes for the mounting bracket. Remove the mounting bracket if you wish if you would like to mount the antenna on an L-bracket as shown in the illustration below. If you have any questions about this, or believe that you have received the wrong antenna, please call us at 1-866-294-1660, or email us at email@example.com.
