3.1 Antenna Placement
Optimal antenna placement is crucial for best reception. Consider the following:
- High Location: Place the antenna as high as possible, ideally on a wall or near a window.
- Clear Path: Ensure there are minimal obstructions between the antenna and broadcast towers. Large metal objects, concrete walls, and other electronic devices can interfere with the signal.
- Dual Color Design: The antenna features a dual-color (white/black) design, allowing you to choose the side that best blends with your home decor.
- Thin Profile: The antenna is ultra-thin (approximately 1mm thick), making it discreet and easy to mount.

3.2 Connecting the Antenna
- Locate the 'Antenna In' or 'RF In' port on the back of your television.
- Connect the coaxial cable from the One For All antenna to this port. Ensure the connection is secure.
- If using the external signal booster, connect it inline between the antenna's coaxial cable and the TV's 'Antenna In' port. The booster typically requires power via a USB connection (check booster instructions for details).

3.3 Scanning for Channels
After connecting the antenna, you must perform a channel scan on your television:
- Turn on your television and select the correct input source (usually 'TV' or 'Antenna').
- Access your TV's menu settings. Look for options like 'Channel Setup', 'Auto Program', 'Channel Scan', or 'Antenna Scan'.
- Initiate the channel scan. This process may take several minutes.
- Once the scan is complete, your TV will display the available channels.
3.4 Using the One For All Assistant App
For assistance with antenna placement and channel availability, you can use the One For All Assistant app. This app helps identify local broadcast towers and suggests optimal antenna positioning for your location.
