Screen Service’s continuous ongoing technical research has made possible the realization of this new series of television transmitters and transposers in 2.5 kW output power versions.
These units are available in VHF and UHF frequency bands and in ultra-compact versions or with redundant amplifiers, with single and double exciters in order to satisfy every need.
The excellent linearity of the stages guarantees optimal performance, low power de-rating when amplifiers are used with digital signals and low power consumption.

Each individual unit within the system is equipped with power supply and protection circuits as well as independent controls to ensure the highest levels of reliability and durability in the system.
A main control panel collects data from all system components and furnishes operating parameters through a practical display, sending them to interfaces for remote monitoring, available for different communication protocols.
