Details
The R70501 SA-51 amplifier is designed for use in SMATV systems based on 5-input multiswitches. It has four satellite inputs and DVB-T/DAB/FM (Terr.TV) input. Placed on the input of the SMATV system, the device amplifies and equalizes the signals before further distribution.
Key features:
- amplification and levelling of IF signals for 4 polarisation-band pairs
- DVB-T and radio signal boosting and levelling
- compensation of attenuation characteristics of coaxial cable
- supplies other components of the installation, such as LNBs, DVB-T preamplifiers, multiswitches or other bus amplifiers
- cast housing ensuring high level of shielding - class A
The use of SA-51/51D amplifiers allows to build extensive multiswitch systems with up to several hundred outlets. Signal level control with switches ensures stability of parameters over time. The cast housing ensures high screening efficiency, which prevents the penetration of interfering signals inside the device.
The unit has a push-pull amplifier in the terrestrial TV path and a built-in switched-mode power supply with short-circuit protection. It is possible to supply TV preamplifiers with 12 V in the DVB-T path.

Designing antenna systems with the use of free software from TERRA - SatNet application. The program allows to prepare the project in graphical form, to determine signal levels in all outlets and verify if they are compliant with standards, and to decide whether to use equalization function of the amplifiers. The program enables the user to archive the designs.
