Very good and unique product of Televes, the output level can not exceed 79dbμV for 1 stream of 8MHz and 50 dbmV input Level, so it is not recommended as a typical mast amplifier of ideal level of 90 to 100 dbμV on 75Ω impedance load. The best description is mast programmable preamplifier. You need a Broadband line amplifier in second stage of 20db 's gain to distribute Rf signal to an installation with pass-throw wall sockets, to gain output second stage level of 100dbμV, and ofcourse with higher Noise Figure by adding a second stage Distribution Amplifier. It is recommend for simple installations with or without terminal sockets and receiving signal from 1,2or 3 different directions Receiving Antennas. I thing that the problem of low output Level is because of combining the Satellite band in the distribution network. Any way i thing that smartkom Amp solves very serious interference problems if you need to receive different channels from different directions with multiple antennas.
No está nada mal.
