There might be some areas where the signal strength could be too high. If so, you may need to connect the antenna to an attenuator. Screw the attenuator onto the “ANT IN” jack.
2 Connect the “ANT LOOP OUT” jack on the HDTV Receiver to the “Antenna In” jack on your TV using a coaxial RF cable.

Before Connecting Your Antenna
During initial installation and setup of your HDTV Receiver, you may need to install a 10 dB attenuator to the Antenna input “ANT IN” on the LST-3100A. The LST-3100A is a high performance, high-gain system intended for operation under normal and weak signal conditions, providing the best reception with its optimum gain. However, there might be some reception areas where the signal strength is too high (e.g. due to close proximity to an unde- sirable signal or transmitter), so you need an attenuator that lowers the incoming signal strength (from the undesir- able transmitter) to more normal levels. This 10 dB attenuator should be used only in a reception area where the undesired signal strength is too high. One of the possible symptoms would be that after your program/channel search, your HDTV receiver does not find all the local digital terrestrial channels available in your area. (You can find HDTV channels/content information for your local broadcast area by going to Zenith website “WWW.ZENITH.COM” and clicking on “HDTV Program Schedule” under HDTV.) Please make sure that before deciding to use an optional attenuator device, you are using an appropriate and properly aligned UHF/VHF RF ter- restrial antenna.
