Rabbit ears are a type of antenna that can be used to receive television signals. They are typically made of two metal rods that are positioned in a V-shape. Rabbit ears can be adjusted to improve the quality of the signal that is received. In general, rabbit ears will work best if they are placed near a window. This is because the signal strength is typically strongest when the antenna is close to the source. Additionally, rabbit ears may need to be adjusted periodically in order to maintain optimal signal strength.
