If the question is whether the smart TV needs an antenna to function, the answer is a resounding no. A smart TV is capable of pulling in visual media from a variety of mediums. It is capable of natively streaming over online subscription services and is also capable of being hooked up to a satellite dish or over a normal HDMI cable. But if the question is whether an antenna can provide TV reception to a smart TV, it absolutely can. Using an antenna to receive content would be not only economical but also a very reliable option for consistent visual quality. The antenna can produce consistent 4K quality while freeing up the RAM in the smart TV for other tasks.
