Podrobný popis

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-924L R70874 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 active 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.
The multiswitch can be powered via "H" lines from SA-901 R70901 amplifier or from local power supply R71465. Each of the power sources can feed a number of multiswitches (one multiswitch consumes max 100 mA).

How to connect a Quatro LNB to Terra multiswitch

Descriptions of the satellite LNB outputs and the multiswitch inputs depend on their manufacturers. To avoid confusion, our movie illustrates the differences and clarifies the issue.

Designing SMATV systems with TERRA SatNet software

Network planning and design with the use of a sheet of paper and a pencil is laborious and entails the risk of error. Free software from TERRA - SatNet - allows to design installations based on the equipment manufactured by the company. 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.
