The FLATenna+ Amplified indoor TV antenna consists of our popular and highly regarded FLATenna indoor antenna and our MicroAmp indoor antenna amplifier. The FLATenna is already regarded as one of the best performing indoor TV antennas on the market. The FLATenna+ will increase signal strength providing increased channel reception and reducing issues with channels having poor signal quality. The included amplifier (MicroAmp) has been fine-tuned for optimal performance when used with the FLATenna. If an indoor antenna is your only option, the FLATenna+ is one of the best options on the market. It is easy to install and provides the flexibility of adding amplification to boost signals in indoor environments where OTA signal is hard to receive.

FLATenna+ was designed to be a low-cost yet high-performance amplified indoor TV antenna. Channel Master customers have had great success with our original FLATenna and the FLATenna+ is an enhanced version that adds amplification. The included amplifier (MicroAmp) uses a USB type connection to power the amplifier directly from the USB port on your TV or from a standard electrical wall outlet. The antenna is easy to install and includes adhesive tabs that make it simple to attach it to the wall without making holes or damaging the wall. The FLATenna+ has an increased reception range of up to 50 miles in areas with strong signals.
