Details
Terra multiswitches of MV series have been designed for medium and large 9-cable SMATV systems, also in multi-staircase buildings (with division into subnetworks).
The MV-916L R70866 multiswitch has built-in amplifiers for terrestrial and satellite TV. The adjustment of the SAT IF and DVB-T (47-790 MHz) gain is made with dedicated switches. In comparison with potentiometers, this solution increases stability of the adjustments.
The DVB-T path has LTE filter for eliminating unwanted signals in 800 MHz band (791-862 MHz) coming from LTE services.
The die-cast housing provides high screening efficiency by preventing the penetration of interfering signals to the unit. High output levels and built-in compensation of the increased loss of signals at higher frequencies in the distribution cables allow for building large SMATV systems with subscriber lines up to 80 meters.

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.
