4G-LTE filter
A 4G-LTE filter is a low-pass filter or notch filter, to be used in terrestrial television (over-the-air/OTA) TV antennas (both collective and individual), to prevent cellular transmissions from interfering with television reception. These filters are usually used for existing facilities, because antennas and amplifiers sold after the new standard was applied may be already be configured to receive, with good signal gain, only TV channels from 14 to 51 of the UHF band, the other higher channels (former TV channels 52 to 83) being attenuated.
