The HDTV antenna amplifier will take a moderate signal that is already in your area and amplify it to a strength that is strong enough for you to watch. This amplified is just what you need when you want to watch clear HDTV without cable service and you have local stations in your viewing area.
The improved gain of the indoor antenna is good when you anticipate distributing your signal with a digital splitter to multiple outlets throughout your house. Since splitters reduce the signal strength that is available at each output, this amplifier creates enough signal to give it sufficient strength. The housing includes a combined VHF/UHF input and a single output for a simpler indoor installation.
