The Channel Master FLATenna with Booster combines the proven performance of the popular FLATenna indoor TV antenna with an advanced adjustable signal amplifier engineered to help improve reception reliability in challenging indoor environments. Unlike standard fixed-gain amplifiers, the included fine-tuning booster allows signal levels to be optimized based on your specific location and installation conditions. Integrated LTE, FM, and out-of-band filters help reduce interference from unwanted signals that can negatively impact television reception. Designed for Smart TVs and HDTVs, the FLATenna with Booster supports 1080p, 4K, and NextGen TV (ATSC 3.0) broadcasts. The ultra-thin low-profile design blends into modern living spaces and installs in minutes, providing access to free over-the-air local channels including news, sports, weather, and entertainment programming without monthly subscription fees. Backed by more than 75 years of over-the-air television expertise, Channel Master has been designing trusted broadcast reception products since 1949.
