The Channel Master 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, pixilation or even channel loss, and can be especially disruptive when using an amplifier with your TV antenna. Channel Master highly recommends using an LTE Filter with TV antenna installations in metro and suburban areas in order to assure optimum performance. If you require an amplifier for your TV antenna installation, we recommend the Channel Master Amplify, a high-end amplifier that includes an internal LTE filter. If you are already using an amplifier with your TV antenna, the LTE Filter will work with your existing installation.
