While an amplifier can boost your antenna’s performance, you may have things in your home that cause interference. Household electronics, such as a ceiling fan, blender, LED or fluorescent lights, or an electric heater can all cause pixelation. Turn off each item one at a time to determine which one may be causing the interference. Additionally, when your antenna is within range of the tower, an amplifier may not be needed. In fact, it may hamper the signal by boosting it past the towers. Try removing the amplifier and performing a channel scan to see if your reception improves. Mounting your antenna as high as possible or near a window gives you the best performance. Note: Any relocation or change to your antenna requires a channel scan to insure you receive the most channels.
