As soon as the signal radiates out of the antenna, 30-40dB of signal is lost Due to path loss, actual signal strength within an amplified space will vary Walls and other obstructions affect signal strength and cause loss A cell phone’s antenna also has loss rather than gain so when reading signal on a phone, results may appear worse Most phones will work reliably with a signal +/- -90dB

Material Signal Absorption Interior Structure Information Interior Wall Construction Material • Signal absorption varies by building material • This will affect the total coverage area of each broadcast antenna • If a high absorption material like concrete or brick, one antenna may need to be used in each room
