A:AnswerYou will need an antenna attached to your TV for the best reception of local channels. A few things like the placement of the antenna, hills or buildings near your home, and other environmental factors could determine the channels that are and are not found by your antenna as well. You do not need cable or satellite service for local channels.
A:AnswerNo from my experience. You can plug in the electric socket at your home, connect to wifi and watch from your favorite streaming services that you are already subscribed to.
A:AnswerYes, this TV does support an antenna connection for your local over the air channels. However, if power is lost in your home, the TV will not be able to operate without power.
