A:Answer Yes, an antenna may be needed for the Insignia - 24” Class F40 Series LED Full HD Smart Fire TV, but it depends on how you plan to use the TV. This model is a smart TV with built-in Fire TV functionality, which means you can stream content from apps like Netflix, Prime Video, YouTube, and more using a Wi-Fi connection no antenna required for those services. However, if you want to watch live over-the-air (OTA) broadcast channels like local news or network TV (e.g., ABC, CBS, NBC), then you will need to connect an HD antenna. The antenna allows the TV to receive free broadcast signals, which can be especially useful if you don’t have cable or satellite service. So, while an antenna isn’t necessary for streaming, it is required for accessing live local channels without a subscription. Patricia | Insignia Support
