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
