New series of masthead amplifiers featuring selectable maximum gain. Thanks to an external selector, it is possible to set one of the two available gain values. Unlike the input attenuator, which is still available for fine adjustment, reducing the maximum gain does not directly affect the amplifier’s noise figure or matching performance. Currently available with an output level of 124 dBµV and maximum gain settings of 30/40 dB. The amplifiers feature a die-cast housing and remote power supply capability via jumpers on the inputs. They are equipped with a practical external plastic cover, highly resistant to impacts and weather conditions, complete with a metal clamp for mast mounting. Versions are available with up to 3 UHF band inputs, with the possibility to customize the cutoff between Band III and Band V. These amplifiers offer excellent linearity and matching characteristics and are equipped with an integrated filter that limits the band to channel E48, eliminating interference from 4G and 5G mobile signals above 700 MHz, in compliance with RED regulations.

Amplifiers are equipped with a jumper for the management of the remote power supply on the outputs.
