- Wall: Mount on an exterior wall, ensuring it is above ground level.
- Balcony: Suitable for apartments or homes with accessible balconies.
- RV: Can be mounted on the roof of a recreational vehicle for portable use.
Safety Precaution: Always exercise caution when working at heights. If you are uncomfortable with roof or ladder work, consult a professional installer. Avoid installing near power lines.

- Mark Drill Holes: Hold the antenna with the bracket in the desired installation location. Use a pencil to mark the positions for drilling.
- Drill Pilot Holes: Drill pilot holes at the marked positions. For masonry or stucco, use a masonry drill bit and insert wall anchors.

4.3 Connecting to Your TV
- Connect Coaxial Cable: Attach one end of a coaxial cable (not included) to the antenna's F-connector.
- Route Cable: Carefully route the coaxial cable from the antenna to your television or TV converter box, avoiding sharp bends or kinks.
- Connect to TV/Converter Box: Connect the other end of the coaxial cable to the "Antenna In" or "RF In" port on your television or digital converter box.
5. Operating Instructions
After physical installation and connection, perform a channel scan on your television or converter box to receive available broadcasts.
5.1 Performing a Channel Scan
- Access TV Menu: Turn on your television and use the remote control to access the main menu.
- Navigate to Setup/Settings: Look for options like "Setup," "Settings," "Channel," or "Broadcast."
- Select Antenna/Air Input: Ensure your TV's input source is set to "Antenna" or "Air."
- Initiate Auto Scan/Auto Program: Select "Auto Scan," "Auto Program," "Channel Search," or similar option. This process may take several minutes.
- Review Channels: Once the scan is complete, your TV will display the number of channels found. You can now browse and watch available over-the-air broadcasts.
Tip: If you are not receiving all expected channels, try repositioning the antenna slightly and performing another channel scan. Since the AT-413 is omni-directional, minor adjustments may still improve reception in some cases.
6. Maintenance
The ANTOP AT-413 antenna is designed for minimal maintenance due to its durable, weather-resistant construction.
- Periodic Inspection: Annually inspect the antenna and its mounting hardware for any signs of wear, corrosion, or loosening.
- Cleaning: If necessary, gently wipe the antenna's surface with a soft, damp cloth to remove dirt or debris. Avoid using harsh chemicals or abrasive cleaners.
- Cable Check: Ensure the coaxial cable remains securely connected and free from damage.
7. Troubleshooting
If you experience issues with your ANTOP AT-413 antenna, consider the following troubleshooting steps:
- No Signal / Few Channels:
- Ensure all cable connections are secure.
- Verify your TV input is set to "Antenna" or "Air."
- Perform a new channel scan on your TV.
- Check for obstructions (trees, buildings) that may be blocking the signal.
- Consider relocating the antenna to a higher or less obstructed position.
- Consult online resources for broadcast tower locations in your area to optimize antenna placement.
- Pixelated Picture / Intermittent Signal:
- This often indicates a weak signal. Try repositioning the antenna.
- Ensure the coaxial cable is not damaged or too long, which can cause signal loss.
- Check for potential sources of interference (e.g., large metal objects, other electronic devices).
- Antenna Not Mounting Securely:
- Ensure you are using appropriate hardware for your mounting surface (e.g., anchors for masonry).
- Verify the mounting bracket is correctly assembled and attached to the antenna.
