Top view
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.
Distinguishing features
  • 9/24 multiswitch for systems with radial topology
  • Built-in cable loss correction
  • Groups of outputs with different output levels
  • Isolation between inputs better than 30 dB
  • Power for optional terrestrial TV preamplifier
  • Active terrestrial TV path with LTE filter (47-790 MHz)
  • Die-cast housing guarantying high screening efficiency
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).
