Wireless Sensor Network
2.1.5 Antenna Options
All CWS wireless sensors contain a built-in 0 dBd 1/4 wave antenna. No other
antenna options are available for the wireless sensors.
The CWB100 Wireless Base Station has a RPSMA connector for use with one
of several models of antenna. The base station does not automatically ship
with an antenna, so one must be ordered as a separate item. Antenna options
available for the CWB100 and CWB100A include the following:
Model Description
15730 900MHz 0dBd Omni 1/4 Wave Whip Antenna w/Right Angle
15731 900MHz 0dBd Omni 1/4 Wave Whip Antenna, Straight 2 inches

Larger outdoor antenna models require a cable to connect to the CWB100.
Available options include COAXRPSMA-L LMR195 cable and COAXNTN-L
RG8 cable. A surge suppressor kit, part number 14462, is required for
connecting the COAXNTN-L cable to the CWB100.
