The OMWT-REP-900 repeater is
supplied standard with a 1/2 wave
monopole antenna. For longer
distance outdoor use, optional
Omni-Directional and YAGI
directional line-of-site antennas
are available.
Since the radio transceivers can be
individually addressed for networks,
several OMWT-REP repeaters can
be used to link clusters of OMWT
Series Wireless Transmitters to a
centrally located OMWT-XREC-SER
or OMWT-XREC-MOD receiver.

The OMWT-REP-900 Wireless
Repeater is a 418 MHz RF receiver
with an integrated 900 MHz
transceiver. It receives CRC-16
error-checked data packets from all
OMWT Series 418 MHz Wireless
Transmitters and other 900 MHz
transceivers within its range,
and then transmits the data
via the built-in 900 MHz radio
to an OMWT-XREC-SER or
OMWT-XREC-MOD receiver. Data
received by the OMWT-XREC-SER
receiver with serial interface can be
displayed and logged using the
OMWT-SOFT Windows Software.
By utilizing 900 MHz frequency,
the OMWT-REP allows the range
of the OMWT Series Wireless
Transmitters to be extended up to
395 m (1300') indoors and up to
32 km (20 miles) outdoors.
