What to consider before purchase

• Confirm that your local broadcasts use the DVB‑T2 standard.
• Check that your TV or display has the matching input connections required by the tuner.

• Decide whether you need additional features (streaming, recording, apps) that this tuner does not provide.

Usage recommendations

For best reception, install a properly oriented external antenna at an elevated position and perform a channel rescan after any antenna adjustments. Keep firmware (if applicable) and on‑screen settings up to date, and position the tuner close to the TV to minimise cable runs and signal loss.
