i cant hook up the digital adapter box to smart tv wont get any channels
Hooking the small digital adapter box to a HD smart tv, the box can only use the coaxial cable connected to the antenna input on the new TV set to channel 3. You will not be able to get any HD channels that way.
you really need to upgrade to at least a HD cable-box. To use the "smart tv's" apps you will also need high-speed Internet of at least 15 to 20 Mbt's/sec. for HD signals.
