Getting good UHF reception can be more difficult than VHF. ƒ If you're getting marginal reception of digital signals, both the picture and sound might freeze or break up to the point that it's not watchable. If you're really on the fringes- either too far from a tower or with too many obstacles in the way-you'll see a black screen that says "No signal." ƒ Reception can vary by channel, depending on the location and broadcast power level of a given station. ƒ Make sure your antenna is connected securely to the TV. ƒ Move the antenna around the room or close to a window. Check the signal strength of the digital channels again. The optimal location may vary by channel. ƒ Use a basic indoor set-top antenna designed to pick up both VHF and UHF. OR Use a set-top antenna that has a built-in signal amplifier.
