A: You will receive all free-to-air DVB-T and DVB-T2 broadcast channels available in your region, which can include local news, sports, entertainment, and public broadcasting in HD and 4K quality — completely free with no subscription required.

Q: Does it work in countries outside of my home country?

A: Yes. The antenna's cross-border capability and wide-band frequency range make it compatible with DVB-T broadcast standards used across Europe, Asia, Australia, and many other regions, making it a great travel companion.
