Mast amplifiers characterized by a die-casting mechanics and supplied with an external shock-proof plastic protection equipped with a metal clamp for attachment to the mast. Designed for connection to VHF and UHF antennas. All the versions of the range have output level of maximum 119 dbµv, differ for gain (up to 30db) and number and type of inputs. For each input is provided the regulation of the signal using constant-impedance attenuators and the possibility of providing the voltage of 12vdc to a possible external preamp. Strengths are the shielding level, the gain linearity and the low noise figure. Versions with separate BIV and BV inputs can be requested with the custom cutting frequency. All models are perfectly compatible with the new transmission standards, and, thanks to the integration of a special selective filter, with the current DTT UHF band (470... 694 MHz) reduced following the reassignment of frequencies to LTE/5G telephony operators.
