Chapter 9
Enclosure Selection and
Mounting Methods
This chapter will discuss the recommended methods for mounting the RFID
antennae and housing the system components.
9.1 Initial Considerations
The device will operate outdoors, fully exposed to the elements. It is
expected to operate in these conditions for extended periods of time,
without maintenance.
Wind will affect the vertically positioned antennae if they are not
sturdily mounted.
Rain and sea air will cause corrosion to any exposed metal components.
Prolonged exposure to the sun causes many plastics to become brittle.
Sealed, dark enclosures will heat up to high temperatures if exposed
to the sun. Such high temperatures may adversely affect digital clo ck
circuits and resonant circuit tuning.
The uplink module uses an internal antenna. Reception is poor if the
device is placed on the ground.
