Your cart is empty.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.

Still can't get but a few channels and it still interups my signal when I turn on my LED lights. So I have to replace my LED bulbs with incondescent bulbs if I can find them. 2 days later I relocated my antenna and removed this unit from the line. Rescanned the TV now I get 76 channels!! And it is far enough away to where my LED light don't affect the signal now.

As an amateur radio operator (HAM) my new HF radio was causing a little interaction with my HD Home Run TV receiver. Since my coax for both devices enters the home very close to each other I needed a bit of extra filtering. After installing this inline on my coax for the TV I have not had any interference with the signal. Works as expected.

I used this high pass filter to prevent my FT8 transmissions overloading the OTA TV distribution amplifier.Before I added this filter the TV would go to blank screen when transmitting at 10W. Now there is no change to the TV no matter what power level I transmit at.

Worked for me, prevents interference on living room TV when transmitting 100 W from my HF rig nearby. Tested 80 m to 10 m.

I bought this to block interference over my TV cable from the antenna, caused by a substandard LED security fixture mounted nearby. It made no difference at all. I sent it back. Perhaps this device is not calibrated to block that particular type of interference? I don't know.

The logs from my TV tuner box don't show any improvement from the noise generated by nearby RF signals vs this not installed.
