3. Setup Instructions
Follow these steps to properly set up your ANTOP AT-800SBS antenna for optimal reception.
3.1. Site Selection and Antenna Placement
- Check Available Channels: Visit dtv.gov to confirm available channels in your area and locate broadcast towers.
- Consider Obstructions: Areas with large obstructions like valleys or mountains may reduce effective range.
- Initial Placement: Place the antenna on a window for initial testing. Try different locations, positioning the antenna as high as possible.
- Indoor/Outdoor Flexibility: The antenna can be used indoors (table stand, wall mount) or outdoors (pole mount).

3.2. Connecting the Antenna
- Connect Coaxial Cable: Connect the coaxial cable from the antenna to the 'ANT IN' port on the Smart Boost System amplifier.
- Connect to TV: Connect another coaxial cable from the 'TV' output on the Smart Boost System to the 'Ant In' or 'Cable In' port on the back of your HDTV or TV converter box.
- Connect Power Adapter: Plug the power adapter into the Smart Boost System and then into a power outlet.
- Second Device Connection (Optional): If connecting a second device (e.g., FM stereo, second TV, streaming device), connect a coaxial cable from the 'TV/FM/Device' output on the Smart Boost System to the respective input on your second device.
3.3. TV Setup
- TV Input/Source: Set your TV's input or source to 'Antenna' or 'Air'.
- Channel Scan: Access your TV's setup menu and perform a 'Channel Search' or 'Channel Scan'. This process may take several minutes.
- Rescan After Relocation: Always rescan for channels after moving the antenna to a new position.
4. Operating Instructions
4.1. Adjusting Reception with Smart Boost System

The Smart Boost System features an adjustment dial to optimize signal reception based on your location's specific needs. Turn the dial to balance the reception range from 0 to 85 miles.
- Short Range (within 35 Miles): If you are very close to broadcast towers, a lower setting (closer to 'MIN' or '0') might be better to prevent signal overload.
- Long Range (up to 85 Miles): For greater distances from broadcast towers, adjust the dial towards 'MAX' or '85' to amplify weaker signals.
- Fine-tuning: Experiment with different dial positions and perform a channel scan after each adjustment to find the optimal setting for the best picture quality and number of channels.
4.2. Using the FM Antenna Feature
The integrated FM antenna allows you to receive local FM radio stations. Connect the 'TV/FM/Device' output of the Smart Boost System to your FM stereo receiver's antenna input. Tune your FM receiver to scan for available radio stations.
