DBC0021F3V22-2

DIPLEXER 1800/2100

The Kaelus DBC0021 combiner provides diplexing of 1800 and 2100MHz bands wherever both signals are required on a single output. This may be at the BTS end of the feeder or at the antenna, saving infrastructure capital expenditure and improving network reliability.

FEATURES

  • Combines 1800 and 2100 bands
  • Options for bypassing DC and AISG internal to the diplexer
  • Single or dual configurations available, suitable for indoor/outdoor use, wall or pole mounting kit
  • Built in lightning protection on all ports
