Details
The SA-51D R70511 multiswitch bus amplifier is designed for use in SMATV collective systems. Equipped with four satellite inputs and one DVB-T/Radio input, it allows to amplify and equalize signal levels for each of the polarization-band pairs (satellite TV) and terrestrial TV. It is used as an interstage amplifier in selected points of the installation (fed via the H-polarisation signal lines from the SA-51 amplifier) or as an input amplifier when the R71465 power supply is used to feed it.
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
- supply of other elements of the installation, such as: LNBs, DVB-T preamplifiers, multiswitches or other bus amplifiers (in the case of connecting power supply R71465)
- cast housing guaranteeing a high level of shielding - class A

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.
