This can cause channels with dropped packets and poor quality to appear as a channel with five green dots. In this scenario, the first step is to remove the amplifier, and begin troubleshooting your antenna without an interfering over-amplified signal. WebTV antenna signal strength is measured in NM (db), or noise margin in decibels, and Pwr (dBm), or power ratio in decibels-milliwatts. The first measurement tells you how "clean" the signal is, meaning how much residual static not associated with the actual program is included in the signal. The second measurement gives you the actual signal ... can allah change my exam results
