4-Way Antenna Splitter
Data Sheet L001667 August 2003
Description
The 4-Way Antenna Splitter allows four
RAD-ISM-900 receivers to share a single
antenna. Designed for use with RAD-ISM-
900 receivers, RAD-ISM-900-UD-1TX/2RX-
BUS mode (2867571) receivers, which are
pre-programmed to receive only. These
splitters can also be cascaded together to
connect a maximum of sixty-four receivers
to one antenna. For best performance when
cascading, the signal should not pass through
more than three splitters before reaching a
receiver. This DIN-rail mount product, with
MCX(F) connectors for both the antenna
and receivers, will perform amplification and
impedance-matching functions, and operates
across a broad power supply and temperature
range.
