Now you are ready to place the reflector onto your antenna. Slide the antenna into the center of the X you made in the cap and then force the bottle down over the antenna until the top of the antenna is level with the top of the reflector. Now you place your antenna in a high place and experiment with it by turning it until you see a boost in the signal strength on your computer. This reflector is good because it covers the entire length of the vertical antenna and is very adjustable both right to left and in and out too.
