Common secondary features of DTAs (Digital TV Adapters) – also commonly known as converter boxes or decoder boxes – include recording and scheduling capabilities, a built-in clock, program guide, and support for closed captions and multiple languages – in fact, these are virtually standard on these devices, though the level of sophistication of each of these features may vary from model to model. That’s why I’ve focused less on including models based on their display specs and other technical features, and more based on durability and removing models with other issues, as poorly designed devices are often prone to overheating, and is one of the reasons I’ve removed the Leelbox models, despite being fond of the brand myself, and added off-brand models like the Ubisheng U-003 instead.

Antennas themselves won’t discriminate between digital and analog channels, though most OTA channels have switched to digital format in recent years, meaning that they tend to broadcast on the UHF band, and the way they send data is also different, and a lot more efficient – data is sent in packages and takes up less bandwidth than analog transmission.Īs analog TVs can only display 480i, the maximum support resolution may largely be irrelevant in the vast majority of applications, unless you're using a computer monitor or other digital display.
