LTEfree filters are designed for the attenuation of signals transmitted over the mobile phone band with a frequency higher than 790 Mhz. type and field of application. They are all made of die-casting, with F or IEC connectors.The two best performing models, with regard to the steepness of the cut between the TV band and 4G band (LTE), are made according to the ultimate technology and comply with the specifications included in the CEI 100- 7 guide (typical case). All the others have a less pronounced transition, are made with LC-type cells, and can be used to integrate the models described above.
