Product Information

Overview

The Channel Master Indoor Antenna Booster is a professional-grade signal amplifier engineered to enhance the performance of indoor TV antennas by boosting RF signal strength up to 30 dB.  It features an integrated three-mode fine-tuning mechanism that allows users to select between different signal characteristics to help improve reception on certain channels.  Because over-the-air broadcast signals vary in direction, frequency, and strength, the tuning mode that benefits one channel may differ from the mode that helps another. This flexibility allows users to experiment and find the setting that delivers the most stable reception across their local channels, helping to reduce pixelation and minimize interference caused by a poor signal-to-noise ratio.

Designed and built with Channel Master’s decades of broadcast expertise, the Indoor Antenna Booster includes FM, LTE, and Out-of-Band filters to prevent unwanted frequencies from being amplified, maintaining a cleaner and more stable RF environment for digital television reception.  Its ultra-low noise figure ensures the signal is amplified cleanly, supporting more reliable tuning and reducing the likelihood of intermittent reception issues.

The Booster includes a built-in power-status LED indicator for easy confirmation that the unit is powered and functioning.  It comes with an integrated 6-foot power cord and a detachable high-quality 6-foot coaxial cable for convenient installation.  Optimized for use with all Channel Master indoor antennas including the Channel Master FLATenna, this amplifier delivers consistent, dependable performance and helps stabilize digital TV reception, backed by Channel Master’s trusted engineering since 1949.
