This is the omnidirectional indoor antenna with a built-in amplifier that pulls in HD, 4K ultra HD, and standard television signals from up to 50 miles away. Ideal for “cord cutting” in urban areas where broadcasts emit from multiple locations, this antenna provides a free entertainment alternative to costly cable, streaming, and satellite channels. It scans channels in a 360º field, enabling you to receive more signals than directional antennas that only focus on a narrow band. It automatically scans and locks in Over-The-Air (OTA) signals and has a built-in filter that blocks interference from mobile devices. The ultra-thin antenna mounts on an included stand or can be hung on a wall. As with all antennas, reception will vary depending upon the distance from the station’s transmitter, geography, and your home’s construction. Older analog televisions require a digital converter box. Includes coaxial cable. Plugs into AC. 13" H x 9" W x 1/8" D. (3 lbs.)
