What is a good signal strength and quality?
Signal strengths can range from approximately -30 dBm to -110 dBm. The closer that number is to 0, the stronger the cell signal. In general, anything better than -85 decibels is considered a usable signal.

Why does my HDTV signal have a high signal strength?
Similarly, amplifying a weak HDTV signal can result in a high signal strength but too much noise to decode the digital data correctly. Use the Signal Strength for a rough idea of direction, but align the antenna for the highest Signal Quality, ignoring Signal Strength.
