2. Mounting the Antenna
- For Pole Mounting (Outdoor): Use the U-bolt and associated hardware to secure the antenna bracket to a vertical pole. Tighten all nuts firmly.
- For Wall Mounting (Outdoor/Indoor): Use the wall mount bracket and screws to attach the antenna to a flat surface. Ensure the surface is sturdy enough to support the antenna.
- For Indoor Stand Placement: Attach the antenna to the provided stand and place it on a stable, flat surface.
3. Connecting the Antenna
- Connect one end of the 5-meter coaxial cable to the antenna's F-connector port.
- Connect the other end of the coaxial cable to the antenna input (ANT IN / RF IN) on your television, set-top box, or DVB-T2 tuner.
4. Powering the Amplifier
The integrated low-noise signal amplifier requires power for optimal performance.
- Connect the USB power cable to the amplifier unit.
- Plug the USB end of the cable into a USB port on your television (if available and provides 5V/550mA) or into the provided USB power adapter.
- Plug the USB power adapter into a standard electrical outlet.
Note: Some televisions can power the antenna directly via their USB port, eliminating the need for the external power adapter. Check your TV's manual for details.
Operating Instructions
Once the antenna is installed and connected, follow these steps to receive signals:
- Turn on your television or DVB-T2 tuner.
- Access the menu settings on your TV/tuner and navigate to the "Channel Scan" or "Auto Tune" option.
- Initiate the channel scan. The antenna will automatically detect available DVB-T2, DAB, and FM signals within its reception range (up to 80 km from the transmitter).
- The integrated LTE filter will automatically block unwanted mobile data signals (4G, 5G) to prevent interference and ensure clear reception of TV and radio broadcasts.
- Once the scan is complete, you should be able to access all available channels in Full HD resolution where supported.
