2 INTRODUCTION TO FDAP
Antennas
FDAP1/FDAP2 uses dual antenna diversity to improve communication reliability in severe multi-path
environment. This helps in improving radio coverage and provides robust communication links thereby reducing
infrastructure cost and cost per wireless field device.
FDAP1/FDAP2 has integral omni-directional antennas and it also supports a variety of high- and low-gain
directional and omni-directional antennas to provide flexibility in installation and to maximize performance of
the wireless system. Refer FDAP1/FDAP2 Regulatory Compliance Guide for details about certified antennas
and the allowable maximum RF output power,.
FDAP1/FDAP2 has integrated lightning suppressors on the antenna ports. The lightning suppressors are
permanently attached and do not require field maintenance. Lighting suppressors are required for all outdoor
installations or indoor installations where FDAP1/FDAP2 may be subjected to lightning surge. Optional
remote mounted lightning suppressors are available for use in application where the remote antenna cable is
exposed to lightning surge.
LED indicators
FDAP1/FDAP2 has three LED's for indicating the status and health of the device. For more information about
LED's, refer to "Table 3.2: LED indicators".
