Boosts Weak Signals When Properly Installed - Compatible with all indoor and outdoor passive (non-amplified) TV antennas, this amplifier improves signal strength and quality when low signal is the actual issue. However, it will not resolve problems caused by interference, multipath, or obstructions, which are common with attic-mounted antennas. For best results, users with attic installations may need to move their antenna outdoors to achieve reliable reception. Please note: TV signal meters often do not reflect true RF levels, so the improvement may not be visible on your screen’s meter. Not compatible with antennas that already have a built-in amplifier or were originally sold with one.

Higher Power Output Compared to Distribution Amplifiers and Amplified Splitters Making it a Better Option For Weak Signal Areas and Installations with Long Coaxial Cable Runs. Compatible with Channel Master Power Passing Splitters (CM-3212HD, CM-3214HD, CM-3218HD) for Whole-Home Distribution to Multiple TV's.

Includes Built-in LTE Filter with ultra low-noise - Blocks Interference From 3G, 4G, 5G Smartphones and Transmitters with EMI & FM Out of Band Filtering (Does Not Pass FM Radio Signals)

Provides higher gain and better results compared to Standard Boosters, Significantly Enhancing Signal Strength and Quality. New design supports current and future digital TV standards like NextGen TV/ ATSC 3.0 and 4k.

Powered Over Coaxial Cable Using the Included Power Inserter, Eliminating The Need for an Outdoor Electrical Outlet. Suitable for Both Commercial and Professionally Installed Residential TV Antenna Systems.

Recommended for Use with High-Quality Passive Antennas and Accessories For optimal performance, we strongly recommend pairing the PreAmp1 with a high-quality passive antenna such as the Channel Master Pro-Model TV Antenna. Using premium coaxial cables and weather-sealed connectors from Channel Master ensures maximum signal integrity and minimizes the risk of signal loss or interference. Low-quality antennas or cables can degrade performance and reduce the effectiveness of the amplifier.
