The presence of LTE transmission on the 800 MHz frequency may have a negative impact on the quality of the DVB-T signal by too strong a signal, causing interference and interfering with the proper reception of digital terrestrial television. In such conditions, single incorrect pixels or distortions of a significant part of the image and sound will appear on the TV screen. The stronger the interference, the more often the image will become "frozen" or even completely disappear from the receiver screen. Such problems will appear suddenly, even with a slight deterioration in the reception conditions of the DVB-T signal.
We can fight interference from the LTE 800 MHZ network quite effectively using the so-called LTE filters. Such a filter effectively suppresses the frequency signal from 790 MHZ to 862 MHZ, i.e. the full range in which LTE 800 MHZ fits. A better solution is to use external directional antennas with a built-in LTE filter.
The new series of BLOW antennas is equipped with an LTE filter, which allows eliminating interference of digital terrestrial television signals from transmitters or devices using LTE technology. This is ensured by the SMT 4G PROTECT system used, which effectively protects against interference interference.
