Most contemporary antennas include some form of adhesive to attach them to your wall or window. If for some reason they lack this option you could try packing tape or poster putty instead. When you install it, you will definitely need to experiment with the placement. A wall may actually be better than a window, depending on the orientation of your living area. Also, if possible, keep the antenna away from magnetic metals such as security bars or the like since they can interfere with your signal strength. If you buy a model with a short, captive lead be aware that you may need to buy a male-female extension lead, and more coaxial cable, to get it to reach your equipment.
