The Best LTE filters for TV antennas: What they are and do you need one?

LTE filters for TV antennas: What they are and do you need one? - LTE broadbans signals interfere TV reception , mostly for Digital TV reception, By using this filter, the TV signal will be clean from interference from the influence of the LTE signal. 

LTE Filters

Amplifiers, LTE Filter

New passive filters have been designed for the attenuation of signals that will be transmitted over the telephone band called 4G (ex Television UHF channels E61 .. E69). These filters differ in selectivity and kind of use. They are all made with die casting or IEC connectors, in order to make them suitable to be inserted at any point in the distribution system. The two best performing models, as regards the steepness of the cut between TV band and 4G band (LTE), are made according to up-to-date technology and respond to the specifications included in the CEI guide 100-7 (typical case). The A+ Class filters are realized by variable capacitors technology. This product is used to solve pronounced LTE interference problems. All the other models have a less pronounced transition, are made with LC-type cells, and can be used to integrate the above described models, or where the risk of interference is not low.
