<p>✔ If you want to improvethe signal of a single digital TV antenna, moving it closer to a window orhigher up on a wall might do the trick.</p><p>✔ The digital TV signal isa ‘line of sight’ signal. Typically, the higher you have your antenna, thebetter the reception. While signals pass through walls and other surfaces, themore obstructions the signal encounters, the weaker the signal and this causessignal disruption. The clearest, most unobstructed view to the broadcast towerswill allow the antenna to perform at the highest level.</p><p>✔ The main disadvantage isthat roofing materials may prevent the antenna from picking up channelsclearly.
