The LTE Filter is designed to clear your OTA TV signal path from the common interference created by mobile LTE signals. The proliferation of LTE signal towers and connected LTE devices are a common cause of intermittent television signal disruption because mobile carriers operate on frequencies that can be very close to your broadcast TV frequencies. These disruptions can result in weak signals, pixelation or even channel loss, and can be especially disruptive when using an amplifier with your TV antenna.
