LTE Filter Improves TV Antenna Signals Block Interference 4G Filter The LTE Filter is designed to clear your over-the-air TV signal path from common interference created by mobile LTE signals. With the rapidly increasing number of LTE signal towers and connected LTE devices across the country, they are now 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, pixilation or even channel loss, and can be especially disruptive when using an amplifier with your TV antenna.
