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).
Distinguishing features
- 9/32 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
- Powering of optional terrestrial TV preamplifier
- Active terrestrial TV path with LTE filter (47-790 MHz)
- Die-cast housing guarantying high screening efficiency (class A)
The MV-932L R70882 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.
