A:AnswerThe rabbit ears of the RCA Indoor Amplified HDTV Antenna extend up to about 30-36 inches. The angles can also be adjusted. You have to re-scan when you change the angle or length of the rabbit ears to get the best reception. I use them to get local programs; otherwise I use streaming via a Fire Stick. The combination works as a cost effective alternative to cable.
