3.4 Physical description of FDAP
The FDAP has a rugged die-cast aluminum enclosure for outdoor use. The primary
subassemblies of the enclosure are the base housing and the cover. The enclosure and all
auxiliary components are designed for IP66 and NEMA Type 4X ratings for protection
against contact with dust and powerful water jet from all directions. The enclosure has
two antenna ports for receiver spatial diversity in the FDAP radios. The antenna holes
use type N threaded bulkhead RF connectors which is inherently watertight to MIL-STD-
202, method 106. The ½” rigid conduit hub has a gasket to seal out water and dust. A
rigid conduit hub, internal and external ground studs, and removable cover are provided
for field installation. Externally accessible IR port and status LEDs allows you to
commission the FDAP and get status information, respectively. The IR port and LED
holes are covered with an outdoor rated adhesive backed Lexan
TM
label. The enclosure
can mounted on a pole or on wall.

reduces number of screws for the cover. The FDAP enclosure assembly also includes
