The Channel Master High Pass Filter improves over-the-air Antenna signals by filtering out noise and RF interference that can disrupt television reception.
The Channel Master High Pass Filter is designed to clear your OTA signal path from common interference for TV reception due to out of band frequencies below 54 MHz This device can be installed anywhere in the signal path prior to the Television tuner or ATSC Set-top box. It is recommended when using a pre-amplifier or distribution amplifier (amplified splitter) that a High Pass Filter be installed at the input of the first amplifier in the signal path. Installing prior to the amplifier will block these unwanted RF signals into the amplifier itself. This can keep your TV signals free of disruptive noise and unwanted signals below the TV Frequency band.
Channel Master highly recommends using a High Pass Filter with installations near Coastal Marine ports or in the proximity of Aeronautical Radio Navigation or Maritime Mobile and Marine Radio location communication. These frequencies as well as some Amateur Satellite transmissions can cause intermittent pixilation or even channel loss and can be especially disruptive when using an amplifier with your TV antenna.
This small device can also free your OTA signal path from household appliances that might emit disruptive RF noise into your signal path. A common occurrence with Indoor Antennas that are nearby common household electronics with power supplies that plug into a wall or power strip.
