DTKom power-doubling line broadband multiband amplifier

DTKom power-doubling line broadband multiband amplifier

DTKom power-doubling line broadband multiband amplifier, controllable

1 input: Return Ch. + MATV

High-power multiband amplifier for CATV operator distribution. Its expanded bandwidth (49 MHz-1002 MHz) offers an user selectable gain of 30/40dB.
Equipped with switchable return channel (5 Mhz-36 MHz), which has a return gain of 28dB when active mode is selected.

The unit can be controlled local or remotely, allowing the technician to test, to modify and to save unit parameters:

  • Via local, with the RJ45 front connector, using the Televes universal programmer Ref. 7234.
  • Via remote, according to B_LAN standards by commands via distribution cable
