A set of channel amplifiers
Every channel amplifier is prepared by the manufacturer for a specified channel - placing an order it is necessary to give the number of the channel.
High-end channel amplifier from ALCAD (prepared by the manufacturer for a specified UHF channel - from C33 to C44). Designed for distributing signals in medium, large and very large MATV/SMATV systems. Due to exceptional selectivity (Cn+2 37dB) the amplifier eliminates signals out of the pass band. It is especially useful when within an installation there are modulators.
Very high maximum output level (2x123dB) allows to build large installations (up to 200 outlets) without using additional amplifiers.
In the case of large systems there should be also used CO-405/705 channel converters.
There are available the following types of frames:
  • ZP-004 R905514 - for 12 ZG channel amplifiers (and power supply),
  • SP-226 R912130 - for 12 ZG channel amplifiers (and power supply),
  • MR-010 R912037 - to be installed in 19" rack - for 9 ZG channel amplifiers (and power supply).
A headend should include:
  • ZG-401 R90517 - the number of the amplifiers is the same as the number of UHF channels used,
  • ZG-601 R90538 - the number of the amplifiers is the same as the number of VHF channels used,
  • ZG-201 R90512 - 1pc,
  • AS-102 R90500 - 1pc for 12 ZG amplifiers,
  • ZP-002 R90552 - the number is the same as of ZG channel amplifiers less the number of antennas,
  • RM-075 R90504 - 2pcs,
  • frame/s - see above.
