Step 2: Position the Antenna
Optimal antenna placement is crucial for reception. Consider the following:
- Place the antenna high and/or near a window.
- Orient the antenna towards the broadcast towers in your area. You can find local broadcast tower information at antennaweb.org.

Step 3: Power the Amplifier (if applicable)
If you are using the indoor amplifier, plug its power adapter into a standard electrical outlet.
Step 4: Scan for Channels
After connecting and positioning the antenna, perform a channel scan on your television. This process varies by TV model, but typically involves navigating to the TV's 'Settings' or 'Setup' menu, selecting 'Channel Scan' or 'Auto Program', and choosing 'Antenna' or 'Air' as the input source.

Operating Instructions
Optimizing Reception
To achieve the best possible reception:
- Experiment with different antenna positions in the room. Slight adjustments can significantly impact signal quality.
- Ensure the extendable dipoles are fully extended and adjusted for the best VHF signal.
- The antenna utilizes TruAmp Technology, which filters noise and amplifies the signal for clear, pure reception.

Understanding Signal Strength
If your TV indicates a "weak signal" or you experience pixelation, try repositioning the antenna and performing another channel scan. For locations 20+ miles from broadcast towers, an amplifier can significantly improve reception. This antenna is compatible with NextGen TV (ATSC 3.0) for advanced broadcast features.

Maintenance
To ensure the longevity and performance of your antenna:
- Clean the antenna periodically with a soft, dry cloth. Do not use harsh chemicals or abrasive cleaners.
- Avoid placing the antenna in direct sunlight or near heat sources.
- Keep the antenna away from moisture and extreme temperatures.
Troubleshooting
No Signal or Poor Picture Quality
- Check Connections: Ensure all coaxial cables are securely connected to the antenna, amplifier (if used), and TV.
- Reposition Antenna: Adjust the antenna's position and direction. Try different locations, including higher spots or closer to a window. Extend the dipoles fully.
- Rescan Channels: Always perform a new channel scan on your TV after repositioning the antenna.
- Check for Interference: Large metal objects, concrete walls, mountains, and power-consuming appliances can block or interfere with signals. Try to move the antenna away from such obstructions.
- Consider an Amplifier: If you are more than 20 miles from broadcast towers, an amplifier can boost weak signals. The included amplifier should be used in such cases.

Missing Channels
- Perform a New Channel Scan: Digital broadcasts can change, or new channels may become available. It is recommended to perform a channel scan every few months.
- Adjust Antenna Direction: Different channels may broadcast from different directions. Try adjusting the antenna's orientation and rescanning.
- Consult AntennaWeb: Use antennaweb.org to identify available channels and their broadcast directions in your specific location.
